[WIP] SuperChis —— Open source GBA TF Flashcart

[ChisBread]

I stand corrected, this thing is almost $90 USD on AliExpress.

What? $90 ChisFlash 1.1?

that is a cartridge flasher, this project is a actual cartridge

I think $90 contains 100% tariffs, ChisLink is not that expensive.

it is only AUD70 here, about USD45-50

Its £43 here. Sorry. Trump tax.

Around 50 € (actually, a bit less) in Europe, it must be the tariffs, crazy stuff.

Can it potentially be shrinked with BGA components to fit in DS lite?

SuperChis has started alpha testing.
Compared with SuperCard:
1. Double the SD card reading speed
2. Better compatibility
3. Better hardware.

Do you have a price in mind?

 

[Hpela]

So cool.

Better compatibility

In terms of memory speed?

I think it should be $20~$25

SuperChis have 1Git of NOR Flash, and support fragment management. This means that there is no need to remove and add ROMs from the end of the Flash (like the EZ Air).
Games loaded into NOR Flash don't lag.

SuperChis have 1Git of NOR Flash

Understood. From your vhd I thought there's still 21 adress lines 4MiB of NOR

I agree, we need a cartridge better than the EZ Flash Omega DE.

I cannot wait to order mine

The most important thing at the moment is to have a cheap and easy-to-use cartridge. SuperCard wasn't enough to do that, so I designed SuperChis.
When SuperChis are proven in the market, I'll start working on better cartridge. Maybe I'll add RTC, rumble, gyroscope, gravity.

It will still be nice to have a new cartridge, I still have my OG SuperCard and it is still working today

The SuperCard team are geniuses at cost control, and they've almost reached the theoretical limit. I just went with a more modern CPLD and replaced the flash with a larger one to make sure we had enough space to store the game.

David will update SuperFW to support SuperChis, and thanks to his support, this has greatly shortened the development time of SuperChis.

RTC

Some MCU to be a bridge between GBA serial protocol and modern RTC(or even mcu's own one)?

Would an ESP32 be a bit overkill? Perhaps an RP2350? Or the OG RP2040?
