Excellent work ... After some tinkering here is my feedback.
A) Launch Menu. Excellent. Simple, clean and functional and works very well. So much better than the previous method used to launch testing of PS1 games.
B) Games testing on emulator.
USB: 320Gig running mass0:
BIOS Tested with: SCPH-7001.bin (NTSC-USA) DO NOT USE SCPH-7502.bin (PAL-EUR) when testing NTSC games. Leads to sound, music and graphic glitches.
1. Castlevania: Symphony of the Night.SLUS_00067 Video Mode: NTSC. Game loads, opening FMV OK, recognises virtual MC, Gameplay = Inconsistent frame rate, lots of graphical glitches. Too slow to be playable. Sound: OK. Use Frame Limiter otherwise voices will not play.
