When I try to use GBC.emu 1.5.29, fresh from the repo, playing a game works fine but, when I go back into the menus, it starts to glitch out, responding to input events in strange ways (eg traversing menu entries out of order and being flaky about acknowledging other types of button presses) before, shortly thereafter, freezing up to the point that I have to hold the Pandora button and kill it to recover the system. That leaves the hardware overlay wedged, so I then have to restart before doing anything involving video or fullscreen graphics.
For comparison, the following PNDs, fresh from the repo, appear to be drawing the icons on the left and right ends of the menu headers as black boxes but, otherwise, seem unaffected by the problem:
... and the following PNDs, which were already on my Pandora from a while ago, work flawlessly.
I am having same problem on CC Pandora. But actually menu is not glitching. It is displaying view from one-before view. E.g. you press space for menu, it still displays game. Then you press down arrow, it starts to display menu. You press one more down. It displays first down view. You press up, it display view of second press down. Then if you press one more time up, it will go up (as if you pressed only once). Shortcuts in the game seems to work, but for example if doing save state would ask of overwrite, it would not display that. If you confirm with button press you can view for short period of time that menu and save gets saved.
not sure about rebirth, but CC panda does not have 4.10 driver. I tried all other available versions via that pnd - they do not work at all.Try to change your video driver. You may have good results with 4.10 using sgx driver r2 pnd.
Now I downloaded 5.15.09 from http://repo.openpandora.org/?page=archive&app=GBCemu_ptitseb Gave it a short play, seems to be fine, no menu glitches, didn't notice problems with game
