How to Flash GBA Games on ChisFlash v1.2

[luis889sv]

Hi everyone,

I recently bought a ChisFlash v1.2 cartridge with rumble support, and it came preloaded with Goodboy Galaxy, which works perfectly. The rumble feature is working fine, and the game boots with no issues.

However, when I tried to flash a different game, like Pokémon Pinball GBA, I couldn't get it to work.
Does anyone know the correct configuration for flashing with GBxCart RW using FlashGBX?

There's a known good configuration in the main thread a few posts down, have you tried using those settings?

What happens when you select "Analyze Flash Cart" in the UI?

I'll try to find the thread you mentioned. As for the "Analyze Flash Cart" option, it's the same one shown in the image above.

ROM Size:32 MiB

Save Type:None

Profile:insideGadgets 32 MiB (28EW256A) + RTC/Rumble

It's the other thread that you posted in regarding this.

I have multiple of them, they work with the pokemon games no issues without having to patch the flash saving like some other cartridges.

This cartridge is actually different to the RTC+Flash cartridge, it uses FRAM and a Rumble, but it seems the FRAM is not getting detected

 

[Lingwendil]

Ah.

I have ordered a 1.2 with rumble+fram to test out for myself I will update when I get it.

 

[Lingwendil]

Which shop did you order from?

I have not yet, was looking for a trusted source to avoid building my own.

this is when loading the cartridge in FlashGBX

after writing the same rom.

running SRAM test

the game does not have rumble enabled, you need to patch it with https://www.romhacking.net/hacks/6256/ also to get rumble working

works perfectly after that


if your cartridge is still reporting no save, try force the save type to 1Mbit unlicensed SRAM then write a 1Mbit save to it (a pokemon save) then run a test on that

Can you send us (me) a screenshot of the analyzation info, with the results window expanded?

the game needs to be patched with a custom patcher, not gbata for 1M Flash to 1M SRAM

https://github.com/bbsan2k/Flash1M_Repro_SRAM_Patcher

also note the RTC(timer) will not work on this cartridge

You can send this screenshot to Lesserkuma (the dev) and he can add support for that cart. But in the meantime, you can choose one of those 4 "compatible" settings, and it should flash fine.

didn't worked, my card is the same as your print

the game boy logo appears, after that white screen, but on pc emulator the rom is ok after the patch

the save type, is unlicensed 1m sram 128kib corret for pokemon ruby?

just an update, I tried this site:
https://gbarompatcher.com/

the game boots, and when I do save, it freezes and there's two leds, one orange and one red blinking, but nothing happens

any hint please?

I just tested it using my system,

dgc@dgc5900x:~/Downloads/ruby$ ./Flash1M_Repro_SRAM_Patcher Pokemon\ -\ Ruby\ Version\ \(USA\,\ Europe\)\ \(Rev\ 2\).gba
Applying patches for FLASH1M_V103
Success! Wrote output_Pokemon - Ruby Version (USA, Europe) (Rev 2).gba

then I wrote the output_Pokemon - Ruby Version (USA, Europe) (Rev 2).gba file to my cartridge and it worked.


so on windows, drag the original rom on to the Flash1M_Repro_SRAM_Patcher.exe file and it will create a patched file that you write.

if you know how to use CLI check it for errors.
