A closer look at the Sony PSP DTP-T1000 Development Kit | MVG

[@bigdumer8997]

Some other memories of early PSP dev: The local wireless mode (called Ad Hoc Mode, I think) used wires in the first batch of dev kits so our QA team had these wires running across the room. Also, the first few iterations of the dev kits had very different screens. I think Sony was trying to figure out which screen to go with - viewing angle was the difference I remember the most. One challenge I remember is that all our development before we got kits was assuming the PSP would run at 333 MHz. However, soon after we got the kits we were informed that the PSP would be locked at 222 MHz due to battery life concerns. This sucked because we had to take out a lot of physics objects which weren't critical to the game but added some extra fun. At some point Sony opened up the PSP to full 333 MHz but it was too late for our launch titles. Also, if I recall, the PSP Dev Kit has 64 MB of RAM which could be toggled on or off using one of the dip-switches. The dip-switches were good for lots of things. I recall we used one for taking screenshots. We were working on a title for Japan launch and all the TRC documents were in Japanese so we had one staff member translate each new version. One scary part was that a TRC for "Sleep Mode" was blank for our entire development. We were nearing Beta and one of the engineers asked QA if sleep mode was causing any issues and the QA guy was like, "What's sleep mode?" Ahhhh! Who could blame him...the TRC was blank and nobody had mentioned it before then. Luckily we didn't have any major issues with sleep mode on that game. On subsequent games, sleep mode testing was a huge part of the QA effort, and a source of some of the most frustrating bugs to fix.

[@Zontar82]

that's an interesting piece of history thanks :) which games did you developed?

[@thisnamehaschangedthanksto8185]

Does sleep mode work kind of like the devkit footswitch? Also, what kind of bugs could be caused by the sleep mode?

[@matthewa2095]

If you don't mind me asking what game did you develop for the psp?

[@bigdumer8997]

@@thisnamehaschangedthanksto8185 Sleep Mode is a switch on the PSP that you slide to pause the game and turn off the screen. The game is basically still running and comes back when you flick the sleep mode switch again. This video has an example: kzbin.info/www/bejne/ppqqn6V3gtOZnsk The bugs were difficult because they were always timing-specific. Put the game into sleep mode during a small time window when saving: corrupt save file. Put the game into sleep mode during a small time window while loading into game: crash. Stuff like that.

@@bigdumer8997 Yep, I know what Sleep mode does. But I wasn't sure if the way it works is similar to that of the footswitch

[@ellaquin]

I love how they sometimes have special looking systems, like with the PS5

[@trinidad17]

There are many odd things in dev kits, some are indeed like seeing the previous version of the hardware where it still was built using off the shelf parts. The PlayStation 1 devkit is like that, aside from a CD emulator card it features a couple of ISA cards that plugged into a PC which contained discrete versions of the console hardware. The 2 cards seem just like a cludge to make up for the lack of space, as in practice the seemed to act like a single cards as they are linked with wires not only on the bus but by the other side of the board too, and a later iteration of the devkit called DTL-H2000 makes away with the twin cards and features a single main ISA board containing the PSX hardware, aside from the CD and sound cards. Some devkits for other systems are something so niche, as you say, that you could see that they were partially manually assembled, some even featuring your run of the mill bodge wire, because they made a mistake and didn't bother to make new PCBs. After FPGAs became cheaper and more powerful devkits began using them instead, and became much less interesting as a result.

[@marthflores3515]

GREAT WAY OF PUTTING IT

[@bigdumer8997]

One issue with the DVD drive is that the read-speed from DVD is much faster than from UMD. To compensate we created a "UMD emulation" mode that artificially slowed the read speed on the DVD build. One time we did a pre-submission to Sony and got our lot of UMDs and they all ran incredibly slowly. Yup, we submitted a build with the UMD emulation so we were artificially slowing the read speed of the already slower UMDs.

The PSP was such a good handheld. It proved with games like the GTA Stories and Metal Gear series that games didn't need to be huge in file size to look and run great. Now I need 100 gigs just to play online multiplayer.

To be fair PSP games were sometimes almost twice as large as Nintendo DS games because they had the space for more. Music video files and the like. Seriously 1.7GB is small by today's standards but back in the PSP days even 700MB games that were pretty sizable making us angry that we didn't own 4GB Memory Sticks.

The foot switch is from T-15Ks, mostly used for profiling so you can play the game and get it to a part that is dropping frames, then you hit the switch to start perf capture.

[@SerBallister]

Seems overly designed and cute, why not use a clickable button or keyboard shortcut in the debugger like normal people ? :D

[@oziphantom9465]

@@SerBallister because you need both hands to hold a controller to play the game. When trying to capture performance data for dips or stalls you have a couple of frames to react otherwise you miss the stall. The foot pedal allows you to play the game and then press the capture button without having to move your hands. resting your foot just on the pedal gives you a very fast response time. From memory the T-15Ks only recorded 7 frames worth of data. Since they already had the pedals they just kept using it on the PSP kits as well. However the system was retired for the PS3.

[@SerBallister]

@@oziphantom9465 Thanks for the detailed response. It did dawn on me after posting that the foot pedal makes perfect sense when both your hands are holding the controller. I never saw a pedal used on ps2 devkits (we had around 5-6 of them) I guess it was optional?

[@captain-cold-muddy]

Back in the day, my employer had the PSP-Movie DevKit. One of the main purposes of having the video output to a CRT monitor was to ensure the video encoding was correct. The PSP screen was able to playback video at 59.96fps but the CRT would playback at 29.97, resulting in the video frames being interlaced. If the video compressionist (back then authors did the video compression - I did at least) encoded the video with the incorrect field flag (top or bottom first), it would be very hard to notice on the PSP screen but on a CRT, it was glaringly obvious. An example of fields being encoded incorrectly and reaching retail is Rob Zombie’s Hellbilly Deluxe UMD.

[@jajabinx35]

I've created quite a few custom UMD movies. Last one I created was star wars VII. It was fun being able to make custom menus and add subs into the video iso. It is pointless, but it had it charms. I still have my custom UMD video iso stored on a drive.

[@TailRecursion]

I had such a love for the PSP as a kid, at one point I tried designing a console conversion of a PSP with a front mounted UMD drive just like this. The difference was that my knowledge of electronics was limited (I was 12 I think?) and I thought I'd need to use a parallel cable to be able to run all of the controller wires to the PCB. Needless to say I was absolutely astonished when I learned about this dev kit a few years later. Feels good to see someone covering it in the flesh.

[@Humbird00]

I remember a crazy setup I did where used homebrew and the video-out of a hacked PSP 2000 to basically play it like a console using a PC controller and a large TV. This actually worked beautifully! The way I accomplished this was to use a custom firmware plugin called RemoteJoyLite to feed PC controller inputs from USB controller hooked up to a laptop to the PSP over USB, and then I just used the PSP's native video-out to display the game on the TV. The irony of this was that RemoteJoyLite's primarily use was sending the PSP's video to a PC, but it also happened to have the ability to send PC controller inputs to the PSP over USB. You could disable the video feed and just use the controller pass-thru feature if you wanted. The reason why I used the PSP's native video-out was that it maintained perfect full speed game performance, likely because it was handled by dedicated hardware within the PSP. Using the plugin's video-out would often slow down the game since it was handling the video feed in software, and the PSP was already busy running a game on top of that.

[@maxinsano7376]

About Component output -- PSP actually did have an official Component (as well as composite) cable out to TV. I've been playing my PSP on TV''s for about 10 years with the component cable. It's pretty sweet!

[@mathieulh]

The DECR-1000 (ps3 devkit) also comes with a footswitch (which incidentally is fully compatible with the DTP-T1000) Sadly, it appears no games (at least none released nor prototypes in the wild) made use of the footswitch (some did made use of the GPIO however)

[@trinidad17]

The GPIO port breakout is nice, this allows devs to build not only custom software but also likely helps with creating hardware peripherals that hook up to their consoles through the expansion ports, and maybe allows some extra debuging/development capabilities in the devkit itself. Not sure about the PSP but the GPIO can used in other systems for things like communication to a custom debugging tool, or even more standard have a mode in which it acts as a regular serial port (SPI) where the devs could use for simple things like printing out logs from the PSP to a PC or even make an interactive console available like allowing control of a GDB session.

I wish people still developed games for this console using these Dev Kits. The games are worth playing and worth to stay in the market as well.

[@WickedGamerCollector]

Thanks for sharing this is awesome to see 😄

[@jormalindgren4865]

I highly enjoy seeing the old devkits 👍🏻

[@X150t]

I was hoping you'd do a PSP Dev kit since you did the NDS. Having had both consoles, I love seeing how similar and different the two brands do things.

[@LalaFafa]

It is always interesting to see these kits in terms of their size. Vita is a handheld device, and this thing is literally a PC case.

[@Metaln00b]

First modded device which i have presented on my school. Love it.

[@ffej4202]

really enjoy these dev kit vids! thank you!

[@TLS2SN]

Interesting video for sure, but it was a nice bonus to see the Detective Conan movie posted for the scarlet bullet on the wall outside of the store, really made me happy!! lol

[@moon27hall]

Great show as always! Thank you MVG

[@bitdevice]

As a game developer, I used the foot switch on the PS3 devkit to toggle noclip or godmode on/off. Was really handy since that is something you use frequently during development.

The PSP is such an amazing handheld console ❤ It amazes me still to this day, especially after I put custom firmware on, about a year ago. It now plays Super Nintendo games, and many more very well, which is mind blowing to me. I also got two external batterie packs for it because the original internal battery isn't as strong anymore, and the aftermarket internal batties are all crap imo. And I got the cable that connects the PSP to the TV via HDMI converter.

I remember working with these back when I did a contract QA gig at SCEA

[@petercklauhk]

that shop is located in the shopping area of the underground of taipei station. some yrs before I got a scratched PS2 DVD that cannot be read from the console or PC. I bring it along with me in one travel trip to Taiwan. There is a shop providing a polishing service for my disc that I cannot find any of similar service in Hong Kong. I finally got the disc readable again and that is fantastic.

[@Bsidheq]

YES GREAT TIMING IVE BEEN INTO PSP VIDEOS LATELY

[@EmilianoFraga]

Amazing. The kit seems very resourceful. Thanks for sharing.

[@jacobbaranowski]

cool that deve kit looks like a old computer I used at school... your the best MVG

[@mateuslira3411]

It makes me curious, this type of devkits are as necessary now days? I mean, it seems unlikely that indie developers, for example, would have access to this type of hardware, it seems to me that developing on PC and using retail hardware (with dev features enabled) would be good enough for most small projects

[@VulpesHilarianus]

Unless you're doing first party driver development it wouldn't be necessary. Old consoles were proprietary tech with few if any compatibility layers, and engines were often custom made due to cost and scale/optimization concerns. It's not like today where you can run a premade engine like Unity, Unreal Engine, or something else on top of a shell that runs a basic graphics API like OpenGL or NVN. In a Switch you're just compiling for an ARM processor and using NVN. The internal firmware of the Switch handles things like internal flash memory access, networking, relative file pathing, and so on. Since you're using standardized hardware that the tools are already developed for and since the firmware handles necessary file and memory functions, that means you can just run the game engine on top and have everything else be handled by what's already on the system. You compare that to the Gamecube, which had no internal firmware other than what was used for the RTC and the memory/disc management. So you had to basically build everything from scratch, from the graphics API on up. You were interfacing almost directly with the hardware. Aggressive Inline for example uses a very specific hardware quirk built into the Gamecube by accident that allows it to play higher quality audio with almost no loading by tracking the audio very sloppily with pretty big sector sizes, since a DVD's sector sizes can only be so small. That same kind of trick wouldn't be possible on PS5 because a game is software run on top of the firmware, on top of the internal hardware management software, on top of the kernel. There's several layers of separation.

[@IronBabyFists]

TIL about the phrase "hotting up." I dig it

[@_retrogamer999]

It's was an excellent console. So many capabilities specially with homebrew and portability.

[@MSDGAMEZ]

The psp was a awesome system

[@mutantmecha]

I got to play with one of these during my second year at aie in 2010 we borrowed it off the 2k guys upstairs. It was insanely easy to get gl code running. I’ve been chasing that high my entire career.

[@volvo09]

Thanks for showing it, that's really cool!
