Wow! Great! I hope it will become a thing also in 1.0s with new screens. If we can find out also what's wrong with the kernel that cannot make regba to work it would be amazing!

That sounds great, tonyjih.

Any chance you could share the source code / patches...?

Thanks

I'll release the source code around 2019 Feb due to some promise to the kernel provider

Nice work Tony, much appreciated.

Quick question, does the double buffer support mean my rs-97 can load roms larger than 70M now? For some reason my 2.1 version device could not use the swap partition with firmware 1.6 so any roms larger tahn 70M will freeze on loading.

Not likely, double buffering refers to the method of drawing pixels to the screen.

This is what double buffer is for.

do existing emulators need to be compiled to take advantage of double buffering or is that handle in the system?

I am using "V2.1 4760B" on "Firmware_v1.6_new21_JZ4760B", everything that I use still works with exception of the PicoDrive emulator. So I am not able to run megadrive or megadrivecd games. Anyone else have the same experience?
