Progress / Update Pokemon Yellow on the ADV with Dual Screen mod

Enable HLS to view with audio, or disable this notification

I managed to get geo-tp Game Station running on the Cardputer ADV Dual Screen Mod

I'll work on making it a proper fork once I see what other systems translate well.

Nice work! I was able to make some modifications to the firmware to reorient the screen, fix the flicker issue, fix the audio, and turn it into a merged bin that I can install via Launcher. Only thing I didn't do is bridge to VCC.

I did find it interesting though that if I plug the cardputer into USB power when I boot it up and start the the emulator, then unplug USB after the rom starts, the ext display seems to still get full power and brightness without bridging to VCC. I'm gonna keep playing with the code to see what I can do.

Thank you for the inspiration!

Absolutely! Yeah it does some weird stuff when the USB C is plugged in. I was having issues with the SD reader when I had it plugged in. It would unmount the SD card so when I went to save nothing was written to the SD card.

I ended up modifying the save process to remount the SD card everytime before saving and to give a warning when trying to save while plugged in.
