    25th anniversary of GameBoy Advance. What are your best memories?

    I played mostly on my PSP (back then I did not know I would eventually work on gPSP emu, ironic :P), but my brother got a GBA when he was like... 8 or 9. I remember that day very well cause he played for like 12h straight and ended up with massive neck pain, could barely tilt his head for a few...

    Hardware SuperChis Prime: How I Fixed the SuperCard SD's Flaws on a Budget

    Yeah we could do that, but the RTC time won't be updated at all. So after you reboot in GBA mode it will be already outdated.

    Hacking DeadSkullzJr's GBA Cheat Databases (Work in Progress)

    Thanks DeadSkullzJr! This is very nice! I have been using your cheats as well as libretro's (coincidentally I worked on libretro GBA cheat database a while back) as a base for the superfw-cheats database (see https://github.com/davidgfnet/superfw-cheats/) I tried to more or less make sure that...

    Hardware SuperChis Prime: How I Fixed the SuperCard SD's Flaws on a Budget

    No RTC Chip, can't "update the RTC". If you are using single pak it's likely that the patches are in the way. Try to flash the game to the internal flash (NOR) and then launch it from there. Mario Kart works fast on flash, slow on RAM. I suspect superchis' flash might be a bit hit or miss...

    SuperFW: a custom firmware for Supercard

    That sounds like a bad flash or something. Seems two of you had a similar issue, odd...

    SuperFW: a custom firmware for Supercard

    Cheats do work on v0.20. I added some more cheats today, find them in the cheats repo. The IGM graphics issue is a known issue. Nothing we can do about it unfortunately. (https://superfw.davidgf.net/docs/usermanual/igm/#caveats-and-known-issues). Savestates suffer from similar issues, they could...

    Hardware SuperChis Prime: How I Fixed the SuperCard SD's Flaws on a Budget

    The cart has no RTC, no way to measure time at all. RTC is emulated very loosely. Every time a game reads "time" we advance a few seconds. Fast/Slow just means how much we jump ahead. I think normal should be more or less 2-3x real time for Pokemon games. But every time you go through a door...

    SuperFW: a custom firmware for Supercard

    v0.20 is out, just a couple of fixes. You guys are very demanding for how little you read :)

    SuperFW: a custom firmware for Supercard

    Cheats are indeed broken, sorry about that! I found this while working on an unrelated thing, lemme fix that in the next release! Edit: keep finding more bugs :D Found some issue with SRAM-based games (the IGM menu won't allow to save the SRAM, there might be ramifications to this). I suspect...

    SuperFW: a custom firmware for Supercard

    Are you using patches for these (ie. https://patchtool.superfw.davidgf.net/)?

    SuperFW: a custom firmware for Supercard

    As per usual, I'm the guy who points at the docs. https://superfw.davidgf.net/docs/usermanual/ds-mode/ You need, of course, a slot1 cart (ie. a cartridge on your "other" cart slot). Something like a superkey or similar.

    SuperFW: a custom firmware for Supercard

    The RTC detection is not perfect unfortunately... sames as the rest of the patches. The patching tool might fail to find the necessary patching points for some games. In my testing I think it did find them for 80% of the pokemon hacks, but not all of them. You can always ask the developers for a...

    SuperFW: a custom firmware for Supercard

    I just updated the issue, forgot to mention this earlier today: Upgrading from v0.18 (and lower) to v0.19 directly is not supported. The header format has changed. To upgrade use the same path as when upgrading from original firmware...

    SuperFW: a custom firmware for Supercard

    Hey there! For those having issues with some specific GBA models, but not with SP/NDS, I'm told it could be an issue with some PCB revision of the GBA. In that case, it would be useful if you report the motherboard revision. Of course, this only applies if your SC works well on NDS or GBA-SP. If...

    SuperFW: a custom firmware for Supercard

    The new web-based patcher seems to work well with many ROM hacks (in particular Pokemon ROM hacks). However I also added support for .sym files, since they are easy to generate (for the developers) and very useful. Check out the instructions...
