Adding Save Batteries to Bootleg GBA Carts!

[@waltzthroughlife]

i recently picked up some secondhand copies of breath of fire and golden sun and i belatedly learned that the bof had a dead batt. quick save is fine (somehow) but a proper save is just not possible. your batt fix vids are the only ones that do not look half-assed. hopefully i will be able to get my bof batt up to snuff soon!

[@DrSalvador555]

I've seen these bootleg games around and wondered if they were functioning properly. After all, I know the Gen 3 pokemon games can still save after the battery runs dry, so I wasn't sure if they even saved properly or not, not to mention Fire Red/Leaf Green didn't use batteries. Or is this just to add a battery to a game after you write over the bootleg's data?

[@esotericsean]

Nice job on this video, really professional-looking. I had no idea this was possible!

[@jensheinke1344]

Hey, I have some fake Pokemon GBA games, that have no battery in it. When I started Pokemon Ruby, it said "The game can be played" (Which should say "The internal battery has run dry. The game can still be played. However, clock based events blablabla") Also I had a premade savefile called "TEST". I deleted all sava data via the shortcut and started my own game. I then saved right when I could, restarted the GBA and my own save was gone, but the "TEST" save still existed strangely. Now I soldered a battery onto the board, and I am really convinced I did this part good enough for the battery to work in the game. I then started the game again and it still said the strange message "The game can be played". I deleted the save data again, started my own save and saved. After rebooting the device, the save is still there and working (although the system makes a short "cracking" sound, while saving the game, idk if that's normal) The clock itself in the game doesn't seem to work, but I can save the game and play now. So my questions are: 1. Is this what we're trying to achieve ? Being able to save your game, but the clock events (berries, clock on the wall, etc.) wont work ? 2. If the answer to question 1 is a yes, then, is it possible to "activate" the real clock ? Or are bootlegs just not capable of doing so 3. Is the strange message, which I never saw in an legitimate cartridge in that form, a sign of a modded Pokemon-ROM ? I thought, may be they wanted to hide the fact that it can't save because of the battery. They just modded the text in the game to be just "The game can be played", instead of "dead battery blabla", because they weren't able to remove the message in the first place !? Thank you in advance. I am trying to get a working bootleg rom, to install a pokemon romhack on it. If this will work, it would be awesome. Bennvenns adapter is coming soon ^^

[@ThisUploaded]

This 'mod' heavily relies on the bootleg game cart actually using the battery contacts in a way that actually powers the Sram. In my experience, most of the bootleg carts I've seen for GBA dont bother having any at all, and save the games to some other type of flash storage. the ROM on the cart is then patched to ignore the battery related functions, and thus the custom message that doesn't say the battery has run dry. So in short, Adding a battery won't help if the PCB isn't manufactured to actually use one. Additionally, you'll need to flash an un-altered ROM of the game to the cart before it will be able to detect the battery even if the cart can detect it.

[@ChubacaSlayer]

I have a copy of Emerald without any battery for over a year and time events still working Just fine

[@enoyna1001]

​@@ChubacaSlayerhow though?

[@PkmHax]

So if i do this will i be able to technically turn a bootleg into genuine by being able to restore a real sav file?

[@LiEnby]

Acturally the battery on the 3rd gen Pokemon games is only used to track the real time clock

[@KyleAwsm]

Yup, I've been meaning to release a follow-up video to correct this. 👍🏻

[@bumpndump9643]

the original pokemon ruby, emerald, etc have baterries not for saving but for the time events, because these bootlegs do not have batteries i'd imagine these events won't happen but by adding this battery, would they happen now?

[@lemonchicken507]

Hey Kyle, think you could do one for GBC? Many thanks

[@giannebaron6139]

Does it work as its own after installing the battery? or do you HAVE to reprogram it?/

[@user-rs1990]

For some protective reason, Pokemon Gen 4 Games are only designed to accept original Gen 3 GBA carts (for when you transfer via Pal Park). Repro/bootleg carts don't work.

[@Phas3s93]

It will allow gba pokemon games to trade with diamond and perl?

[@voltazkai]

Unfortunately both of my bootleg cart are the one that's missing the battery contacts like the one shown on 2:24. What are the extra steps required? Are you going to do a video on how to install a battery on those...or is it better for me to just buy a ruby repro?

[@KyleAwsm]

voltazkai For now, buy a few Ruby repros I think. Would you be willing to send me one of your carts for me to use in a future video? There has been some interest from a few people on the more difficult cart. Just let me know!

Does doing this make it to were you can trade between gen3 and gen4? Does anyone know or have tried to see if this is possible? It would be nice to see a video.

[@chimchar545]

Did you find the answer? I have been wondering this as well

[@Yamchump36]

I have a question. I bought some reproduction carts of all the GBA Pokémon games a while back, and while they save just fine, they don't have a working real time clock. For Fire Red and Leaf Green, this isn't really an issue, since those games don't seem to use an RTC anyways, but this is a major problem for Ruby, Sapphire, and Emerald, since many in-game events rely on the RTC. Does the trick you show in the video fix that issue, or do I just have to suck it up and shell out hundreds of dollars for official cartridges?

[@nickjc1999]

super late reply but no it doesnt fix that, ive done this myself and all it does is prevent the 'dry battery' message. No rtc circuitry inside the bootleg so no clock unfortunately :(

[@techflame6057]

Will this enable real time clock?

[@Jewish.Trickery]

Hey Kyle! I just want to ask you a question! Why do you install the battery exactly? The few I’ve bought before didn’t need a battery to save. Is it for the clock based events? If anyone knows the answer please let me know. Thank you!

[@KyleAwsm]

Hi! Bootlegs don't have a clock chip or xtal, and the battery is to power the SRAM. The reason these carts don't ship with a battery is because these Pokemon ROMs are patched to save to an empty part of the same flash chip that the game is on. The battery is more-so for when you flash unpatched games to the cart. Check out my Joey Gen3 video for more details on flashing bootlegs. Cheers! 🙂

[@ShaggyMetalJay]

@@KyleAwsm does adding the battery make the save format be where I can transfer gen 3 pokemon to the gen 4 ds games?

[@Ataguile1029]

My pokemon cartridge has a SEC KOREA chip, and it saves even without the battery, however, when I reach the end of the game, the save disappears, could this be due to lack of storage space on the memory chip? Can adding a battery solve this problem?

[@jokerblade6719]

[@alubaldini]

i own a final fantasy down of sarrow fake ,can i do this and how many years can work , i hear tha fake cartridges drain in few time the batteries

[@tonimorton]

these fakes apparently use some memory hackery to make the save data store in the rom chip by storing some of the flash code in ram and writing the save to rom they may not even have the sram

[@Scarabaeus15]

Did they never make bootlegs using flash memory, the memory type like on most original carts on GBA? Because that one would save without needing the battery like the real ones (ignoring the clock part). They always are SRAM save modded ROMs?

[@TheCynicalJedi]

I have a knock off Ruby cart with no battery and it has no problems saving and loading, so they 100% exist now if they didn't 5 years ago

there are bootlegs that can support save files without having the cartridge battery right? So what is the point of installing the battery to the bootleg if it already saves the game?

[@rugiXD]

Do u know of any cartridge that comes with RTC? I mean, Ruby Sapphire and Emerald have an internal real time clock RTC and thats why they need a battery so i want to know if those fake cartridges come with that clock or not

[@zacharyrhodge]

Does adding a save battery allow for RTC features, like berries or the day/night cycle, to work in these carts? If not, could you **hypothetically** flash an original ROM onto the cart so that RTC features will work?

[@michellefernandez3155]

yes to the second question

[@JoeytheGrape]

But does it actually work? You could flash the original ROM but these boards are still missing the RTC module and timing crystal, no?

[@michaeldemers2716]

I got Final Fantasy Adventure and had to flash it to English but the battery had a little plastic boot you could just insert it in. It only saves for a while though because after a while it would be dead. I have to use it on my Retron 5 now to have a save and can't play portable. I am getting the new Gba Everdrive mini. So I can play portable again on my GBA SP.

Somebody knows if this can make games like Repro Silver/Gold/Crystal be finished as intended?

(Even if in the credits the ¨SAVING - PLEASE DONT TURN OFF¨ Message appears) Any idea would be great, have finished all those 3 repros but can't continue with the game. (Stuck before Lance even after i defeated him, because that's where my last save was)

[@delta-3856]

Just a quick question about my gba cartridges. So I have multiple real gba Pokemon games that I recently replaced the batteries for, but the new shell I installed them in doesn't have a screw. The cartridge is slightly loose but all I have to do is hold it together when I insert it into my gba. Is it okay to do this or will it damage the game?

[@KyleAwsm]

Delta-38 In my opinion, I think it should be ok, as long as the PCB is held in place within the shell when inserted in the slot. Replacement screws that are the right size for these shells are next to impossible to find, but I'll probably post a video of some sort if/when I ever find a half-decent supply. Thanks for the question!

[@adamcrux6829]

I'm trying to do this to a GBC Pokemon crystal version cart. It does have FRAM save already but the RTC doesn't work. It already has a spot for a battery but the trace to the positive runs to an unpopulated SMD pad. I already know what goes there because it's labeled. My problem is I know nothing about this cart as I literally just got it today. I can't find anyone that has attempted this beside KyleAwsm. So I have no idea if adding these components and battery will make it work or just fry something.

[@KyleAwsm]

It sounds like you bought either a Chinese bootleg Pokemon Crystal cart, or a used genuine cart that someone used for parts before you got to it. I've already tried some things on some bootleg Crystal carts and they're pretty stubborn. Some are even unflashable. If you're looking for a cheap way to play Pokemon Crystal or a ROM hack of it on genuine hardware, AND with operational RTC, check out the BennVenn MBC3000 flash cartridge on our store: highscoretech.myshopify.com/products/bennvenn-mbc3000-rtc-reflashable-gameboy-cartridge-v4 Also, for a few extra dollars, we can flash a compatible ROM that you provide. Hope this helps, and thanks for watching! 🙂👍🏻

[@adamcrux6829]

@KyleAwsm Yup its 100% a china bootleg. I thought the gba cart he was working on in this video was too. I actually already have a couple MBC3000's and I have the Joey Jr too. I just like tinkering and I got this china cart for free. Started playing it and decided I wanted the RTC to work.

Just a minor FYI, when you're soldering you're way better off heating the pads first and then touching the solder to them rather than putting cold solder on the pads and touching the iron to both at the same time. That's why your joints are just balls and the solder doesn't seem to be flowing that well.

[@ghostmasterpresents]

Do you know a way to add a save battery to this type of cart? imgur.com/a/itbYBed It looks like this ROM tries to generate the save file itself for the emulator, so it overwrites whatever .sav file you give it. The save data is there but it isn't a standard save file so it appears to have its own file system. It spreads the save out over different areas as the flash used in these carts are good for around 1000 writes before failure so by spreading it over a huge area, it increases it to perhaps a million writes. So it appears the easiest method would be to just add a battery but it seems I don't have a firm enough grasp on how to do it myself. So if anybody could point me in the right direction, I would appreciate it. Here are the rom files to the game in case somebody wants to try taking a crack at extracting and adding a custom save file back onto this rom type. The save is somehow encoded into the rom since when flashing the game to another bootleg it shows the same save that was on the original dump. I was hoping to find a way to get a custom save back onto the rom itself and flash it back or add a battery to the cart itself and store the save on it. 1st Link: www.mediafire.com/file/wsilscah63ptez2/XYSeries.GBA/file?fbclid=IwAR0ws8fTCtlDzS9rRtJVJYIzSAHH1jeWmPbMy9KCSkSbfw7OASnddfnPtk0 2nd Link: www.mediafire.com/file/0c3fz793z0aehfg/XySeries2.GBA/file?fbclid=IwAR0JCAA7d0ukQLScnvHYKZqcZ_XK9f7k-ElsdgUkBInsHH_eI5-EUgVmF7U (2nd link has another caught pokemon to show difference in HxD analysis)

Hey man, quick question for you. When you use a bootleg GBA game, does it draw too much power from the gba that causes the GBA to shut down? I've looked online to find out but I haven't found anything useful. Thanks, Danny T

should probably use 90% alcohol dont you think?

please tutorial how to make multiROM cart

[@SoupHeavenly]

99% sometimes fries some of these chips. Use light amounts

My cart comes with bridges that are labeled “N” and “Y” and from what I read, it means if a battery is present. What do you think? I am going to be attempting this with a 5 dollar cart from eBay. I have everything except the battery and flux but they are on the way

[@dysphoria-chan]

If only Chinese producers put more effort on this repros... although probably it would cost more if they add batteries.

[@xijinping2956]

The bootleg can can still save without the battery!👍

[@KyleAwsm]

Yes, but only if the game ROM file is specifically patched to do so, like the ones that come on the bootleg carts. Thanks for watching!
