This version is much better than the last. If it continues like this, the GP32 will be a perfect handheld Megadrive (other than cyclone bug). I know it is a WIP but some suggestions below.
1) .ZIP support. MD games are big, it would be nice to increase the amount on a card.
2) saves. otherwise RPGs are not useable.
3) Contrast. The background is still a medium gray. It needs to be BLACK, a space scene background should match the unused bars at the top and bottom of the screen. It should be an RGB value of 0,0,0, always. It tends to look hazy/washed out now especially on the BLU. This one should be a simple fix too just change the values of black to 0, white should be at maximum and everything works down from there.
4) support for long filenames would be nice.
5) it allows for controls to be configured but only for select, a,b. it should allow for right shoulder button to be used if wanted because select shuts off the light on the BLU. So you could have a,b,right shoulder if wanted.
Anyway this is comming along great, thanks for the fantastic work
