To avoid lifting pads, use a low melting point temperature solder and put fresh solder on all of the pads. Add some fresh low melting point solder to the tip of your iron before you start wicking, this will help with thermal conductivity and will start the wicking process. Use flux as you did. But DO NOT press the wick into the board, just let it glide along the surface. Using a thinner width wick (1.5mm) on the small stuff helps as the solder will stay hot on the wick instead of all the heat dissipating into the giant wick which acts as a heat-sink. I do this and *never* lift pads. Also, if you are able to heat the entire package (chip) up and remove it in one go that's also good as then you don't exert any mechanical pressure onto the pads as no prising is needed. Avoid prising whenever possible.

[@MarkFixesStuff]

Thanks for the tips Dominic. I really appreciate it. I’ll do that in the next video for sure!

[@FehNorth]

I can solder but what you did here is beyond my level. Incredible work!

[@MarkFixesStuff]

Thank you so much. Actually I think SMD stuff is easier than through hole soldering but you need the right things so you are probably more than capable of this.

[@FehNorth]

​@@MarkFixesStuff Thank you. After practicing more I'll chane the components in order to make my VA0 support GDEMU

[@underhandedrichard2896]

I just recently looked into modding my dreamcast. Love the fact I found your channel

[@MarkFixesStuff]

I love it too! Thanks for watching and taking the time to comment!

[@tonelander9534]

You must have arms like Popeye now Mark, due to all that speedy tool action.

[@MarkFixesStuff]

Just one arm...

[@danielworley5756]

Black screen isn't awkward, I like it

[@3vi1J]

@1:09 [Picard voice]: There are FOUR screws.

[@MarkFixesStuff]

MAKE IT SO! I NEED A NUMBER TWO!

[@tonelander9534]

I like how you got some solder on the hampton wick as well. Must have been a pain to remove.

[@MarkFixesStuff]

[@Flamelily-IT]

Absolute skills Mark. I wish I had your steady hands on my tools 😉

[@MarkFixesStuff]

There's always 2021.

[@Rockythefishman]

Nice job fixing the pad 👍🏻

[@MarkFixesStuff]

Thanks VV!

[@danielson9579]

I remember that wrapper on lucozade bottles as well 😅

[@MarkFixesStuff]

Crinkly. Used to buy it from the chemist hahah! Just sugar.

[@rae91267]

Oh...So the dreamcast really doesn't have a brain inside! THE COMMERCIALS LIED TO US

[@Jimfowler82]

Haha the wrapping reminds me of lucozade too

[@ctrlaltrees]

Good length here Mark, and I was impressed with the depth that you managed to hit too. But I did come away somewhat unsatisfied... What happened to your infamous innuendos? I was sure you'd try to at least slip one in.

[@MarkFixesStuff]

I have a NO FILTH policy.

[@Colin_Ames]

Great job Mark. In the mid-50s I became ill with the Asian flu that hit the UK, and I drank an awful lot of Lucozade. Can you still buy it? I ask because I live in the US now, and obviously we don’t see it here.

[@MarkFixesStuff]

Yes mate. It’s in loads of sugar free flavours now, playing off of the brand name but they original orange stuff is still on sale as a “sports drink”.

[@KingKrouch]

You can get the devkit Sega Dreamcast boot sequence through a BIOS mod? Not gonna lie, that makes turning it on way more lively than the final boot sequence we ended up getting.

Great job again Mark👍

[@MarkFixesStuff]

Thank you Duggie

[@miikasuominen3845]

Well. There are much smallers wicks, those are much better on those smaller pads. The real problem comes, if the pads have a large ground plane. For those, I would say use something to pre-heat the board. Like a "thermal pad" (don't know if that's a proper term in English)... And heat the board to something like 80 celsius... Though, it there are plastic connectors beneath, be careful. Those might not take the heat... As you said, on your case the pad was not connected to anything, so it really didn't matter. Though I would have also do the "repair", just like you did. Just for the looks of it... "Thicker" flux also tends to make everything easier, though it leaves more stuff on the board. Use IPA to clean them, always. "Running" flux leaves less markings, but doesn't do the job (on most cases) as good as the thicker one. Pick your poison, there is no "right choice". One works better to one and other for another. Train on not important things. You can never know before, if the board has good quality or if thr pads that fly out even with minimal heat and touch... Those can be repaired, though that will always make them look kess professional...

[@MarkFixesStuff]

Thank you for sharing this. Reading your experiences really helps me on my SMD journey. I have a few thick fluxes to try as well. Brilliant tips! Please keep them coming.

[@BMR86]

that ebay link shows the shop is not around anymore

[@MarkFixesStuff]

Thank you. I’ve removed it now.

[@mondherbouazizi4433]

Thanks for the video!! Quite easy to follow and detailed enough to know what to do in each step. A quick question though: Suppose I have a Japanese DC (which I do) and want the menu language to change to English. Does this chip allow me to choose whichever language I want for the menu or it just allows me to play disks from other regions, and the menu will remain in Japanese?

[@yackyyam]

I miss your innuendos lol

[@computercomputer8922]

Thermal pads that old should definitely be replaced.

[@MarkFixesStuff]

Yeah. I need to do that.

[@MarkFixesStuff]

[@JacklapottTv]

What a genius discovery

[@joesaiditstrue]

So would this mod be pointless for someone who has a launch japanese DC? Mine plays the Bootloader discs fine

[@MarkFixesStuff]

it would just be cosmetic really.

[@TheAnimeexpansion]

So I installed my kit and yeah no menu appears, not 100% sure what the next step is. I have a gdemu and ofc don't want to have any issues with it.

[@MarkFixesStuff]

Have you double checked your connections?

[@TheAnimeexpansion]

@@MarkFixesStuff yeah, thankfully got it working, although messed up due to the latest version not running with the gdemu whatsoever. So I'm attempting to get the old version back

[@MarkFixesStuff]

@@TheAnimeexpansion oh no. I’m glad to hear you’ve made so progress though.

[@TheAnimeexpansion]

@@MarkFixesStuff thanks, I appreciate that! Only roadblock now is my sd card reader isn't working. Got a very cheap one a little bit ago and the soldering on the legs is really shoddy!

[@MADFACEMANNN]

Hello! I bought a gd emu 5.15b clone but apparently my dreamcast VA1 (J) bios is protected. and prevents me from loading ROMS (cdi,gdi) from the emulator, sending me to the main menu. the question is, is it possible to replace the bios itself - shown in your video, and will there be conflicts with the GD EMU?

[@MarkFixesStuff]

You can replace the BIOS. I did a video on it and the GDEMU doesn't care.

[@envisk821]

how do you update from v1.031 to v1.032? I see dreamshell comes with v1.031 already but trying to figure out how to load .32

[@MarkFixesStuff]

Sorry. Missed this. I actually burned the update onto a CD-R and installed it from there. Hard to remember now though

[@sagiriizumi8079]

I don't ever clean the pads. Just pop it down and heat it up. Otherwise you get issues like the pads coming off since they're old

[@MarkFixesStuff]

Thanks. This might be the best way from now on. Thank you for watching and taking the time to comment. I really appreciate it.

[@DoctorWhom]

@@MarkFixesStuff If you have trouble with not cleaning the pads, hopefully it makes it into a video. Louis Rossman rips off pads all the time, but he's repairing water damage.

[@MittensDoesThings1991]

16:44 How did you update the bios? Is there a file I need to find?

[@MarkFixesStuff]

@@MittensDoesThings1991 I bought mine programmed. I don’t have this Dreamcast any more because it was lost when my house burned down, but if I recall correctly I just replaced the original chip

[@willl793]

So it just changes the menus and loading screen a little? 🙁 Still cool video I thought the chip would do more stuff though

[@DecibelAlex]

it allows you to play region locked games and backups

[@frankowalker4662]

Nice work on the chip. I hate SMD. :)

Thanks Franko. I'm not keen myself, so I'm trying to expose myself a bit more.

Nice video mate! A question. With this bios , can I boot games from SD adapter without using the CD bootloader? My CD drive died, and Gdemu is quite expensive nowadays, and this looks quite easy to perform and very cheap.

[@MarkFixesStuff]

No mate. Unfortunately. Although you could look out for a cheap cd drive instead - loads of people give them away for little

[@AndyVandercoy]

I just installed my bios and get a black screen sadly. I have a 1.6rev and there was a guide to solder to pin 9 of the ic503 from pin 44 of the bios chip. Also wired from pin one to the same you you soldered pin 1 of the bios chip to. Everything looked well and good, reflowed and continuity and all that. Flex cables fans and all that were secured. The system powers on, disk books and initializes, you here the beep and nothing on any screen I connected to. I got no answer from the ebay seller but it said free 3d dev. And I assumed I could just replace the chip without piggybacking. Any knowledge of where I might go from here?

[@Progressive.G]

[@Levin_Pilot_246]

Guys,I need your help, in the past, I used an Harbor Freight branded 1500 watt dual coil heat gun at maximum temperature like 1124 degree farenheit, but for some reason, I think I killed the old motherboard, because it didn't wanted to boot up, I got black screen, even though it was everything connected properly, no dirty connections at all. Possibly, because this heat gun was for other purposes, like stripping paint, and varnish, and not for electronics, next time, I will use it with the lowest temperature, at 572 degree farenheit instead, once I got a new motherboard

[@wiggy8912]

I'm laughing at all that work to replace a non-connected pad.

[@MarkFixesStuff]

Yeah. My house burned down after this video and it was all destroyed anyway!

[@DecibelAlex]

careful when lifting the chip. It's very easy to ruin the PCB

[@MarkFixesStuff]

it can boot games from the cd whit the bios custom ?

[@Cloud9551]

What was the point of this? Waste.

[@MarkFixesStuff]

The point is to enable booting of backups and MIL discs on machines that don’t have that capability, such as later VA1 models that had the MIL booting loophole removed. I’m not sure what was wasted? 🤔
