I am using cfw 3.80 m33-5. I dont want to upgrade since i got other firmwares and emulators runing.
I tried snes9x but wont work.
I am running kernel 1.50

Youtube also wont help.

I would highly highly recommend upgrading to 5.00M33-6 (the latest custom firmware that supports 1.50 kernel) or 5.50GEN-D3 if you don’t need to keep 1.50 (which is heavily going out-of-date)

for the latest (last i checked) snes emulator, go to google.com and search for "Snes9xTYL0.4.2mecm"

this one will run under the 5.00 / 5.50 kernel and not the 1.50, but is certainly much more up-to-date than "Snes9x"

if you need more help you could always ask another question here specific to that problem
