In the "handy" many functions are marked as inline. Does this have a major impact on performance, where the values are used very often? * Perhaps the emulator uses "wrong" value-types, 32bit instead of 16bit, which are not necessary. * I have activated in the sdkconfig that all ram can be used through malloc.

sd/roms/lynx/_debug.lnx (tested with Chip's Challenge and Ms Pacman) On those devices the main problem was the caching, the inline functions and how the used variables where declared (with the compiler I used at that time).įor testing this port the following files must be on the SD-card: On the GP32 I managed at least that Chip's Challenge ran playable with sound. On the GP2X the emulator ran at "full speed" (perhaps with frameskip, but the sound was ok) for as far as I remember with all games. Finally I got it running without an image. First I ran into issues with the ram, I didn't know anything about this on the hardware. It's really a long time ago I ported the "handy" Atari Lynx Emulator to the gp32 and gp2x.
