No one knows, dude. We don't have contact with the ppl that make downgraders. I tried emailing MPH, telling him he was awesome for making all the tools he has released, but he wouldn't reply. So... that leaves us here, with no information on a 2.50 downgrader. IMO, there won't be one b/c of the system security of the 2.01 FW and above. Too tricky. I think MPH just got lucky...
yea, someone needs to let me know when they figure out a way to run Coast 2 Coast (OutRun) on a v1.50. *Please*
and YES. I have already tried RunUMD/Genesis. Don't work. Unless I can get a firmware dump of 2.60 which I don't think is possible, then I won't be able to try MPHGL.
"IF YOU UPGRADE TO THIS FIRMWARE VERSION YOU WILL NOT BE ABLE TO PLAY HOMEBREW. THERE IS CURRENTLY NO WAY TO DOWNGRADE ONCE YOU HAVE UPGRADED TO 2.50, SO YOU WILL BE STUCK WITH THIS FIRMWARE VERSION.
