rgbds VS ENGAGE

This is a game jam where you make a Game Boy game in three months. If you don't know a lot of programming you can use GB Studio, you can learn the nitty gritty of how the Game Boy works by using assembly programming with RGBDS, or you can use C with GBDK or ZGB.

You can compile the ROM's back with rgbds: https://github.com/gbdev/rgbds

Here you can see how bank switching works.

Probably not exactly what you want, but maybe worth checking out just in case: https://rgbds.gbdev.io/

Clone the specific version of rgbds we need (0.2.0 and 0.2.1 had segfaults on linking, but 0.2.2 seems to work just fine) git clone -b v0.2.2 https://github.com/gbdev/rgbds.git cd rgbds make cd ..

rgbfix is part of rgbds

Could be, take a look at the batteryless Gameboy for example: https://github.com/TUDSSL/ENGAGE

But I don't know how to design at all, and RAM on its own is a lot harder to integrate into a board, and isn't as simple as soldering 8MB PSRAM on a Teensy pad. That said, this academic group did that with An Apollo3 MCU: https://github.com/tudssl/engage The Apollo4 will have 1.8MB SRAM, which I think will be more than a lot of these boards have https://ambiq.com/apollo4/ at much lower power. The Apollo3 Blue+ has 768K SRAM.

Thanks for the analysis! I am not an engineer so I try to glean as much as I can from this so hopefully I can find the right components and discard the things that aren't needed. This board here used the same MCU in my link above: https://github.com/tudssl/engage so I am looking for ways to turn it into a solarpowered laptop with e-ink that doesn't shutoff/sleep every 10 seconds but can idle 24hrs using a few of these https://www.powerfilmsolar.com/products/electronic-component-solar-panels/indoor-light-series/ll200-2-4-75. I had considered the ESP-32WROVER with 8MB RAM but the PSRAM is not as low power as FRAM.

I became curious because this project ran a game on a 48mhz processor using FRAM: https://github.com/tudssl/engage
