Pokemon Mini

[Moondandy]

I've had one of these for about a year I picked up cheap on a whim and it's a fun little thing. It didn't have a lot of games, but had since obtained a strong homebrew scene. For people who don't know it is the world's smaller handheld console that had cart releases, all of the games were Pokemon themed.

Reading more about the hardware today, it might be a relatively easy core for someone to develop.

Technical Details:
CPU 8-bit, 4 MHz Seiko (now Epson) S1C88
96 x 64 pixel monochrome LCD
Game Pak (512KiB cartridge)
Internal BIOS of 4kB
Internal ram 4kB (shared with video subsystem)
21-bit cartridge bus
256 hardware register; in most cases Open-Bus registers

The console has already been emulated several times, and there is a lot of documentation about development tools.

The S1C88 chip also has a manual

For such a small piece of kit it has some interesting hardware features
IR for playing 2 player games with another handheld (would not be ale to be supported on MiSTer)
Real-Time Clock (supportable)
Reed switch for detecting shakes (could presumably be mapped to a button press)
Motor for rumble support (could be supported one day when supported in framework)

Do people think this could be doable on MiSTer?

I second this. Not to be an armchair developer, but this seems like it'd be a relatively easy core to create. The most complicated aspect is probably the real-time clock. It seems to be about as powerful as the Arduboy so I'd say it's most likely doable.

RTC might not be too difficult, FPGAzumSpazz had implemented it into the GBA and GB/GBC cores. Be great to see his take on this cores viability.

Looking forward to see someone tackle this neat little console!

Hopefully someone does take it on, it does look like all the info needed is out there, just needs someone with the skills and a desire to have a go.
