i dont think it has to do with the frequency at all. possibly a dirty cart connector or something silly. can you test a different game besides tetris thats not on the EMS cart? also, after modding about 40 back PCB's about 3-5 of them were sour to start of with, there may be a possibility that the back pcb could be bad =/
I've tested my keyboard with all 127 of my hardcopy games, and all of them work. The flash cart will boot images on the keyboard without a problem. Anything loaded onto the cart that requires loading from ram or accessing higher address lines, either doesn't boot, or crashes almost immediately. The flash cart works without any problems on all of my other hardware, including my Super Gameboy and Gameboy Player. I've tested with other motherboards and cartridge ports (in multiple combinations) but always with the same result. I've been scouring the internet for information regarding this problem, but despite all of my masterful google-fu, I've come up with nothing, and appear to be the only person to try this.
