Mame4All PSP v4.9r2

Hi guys,

I'm new to the forum so if I've made any mistakes then im sorry.

I've recently installed this on my PSP Phat 5.00 m33, (downloaded Mike hacks version as I had trouble running the other version of 4.9r2)

Anyways it came with 2 demo's and they work perfect, now the only other game that I was totally addicted to as a kid was Tumblepop and I would have loved to play this on my PSP. So first I checked in the game list and it says Tumblepop is compatible, so I placed the tumblep zipped file in the rom folder and when I ran the emulator it says the following:

Unable to open ROM
Error reading ROMs
Unable to initialize machine emulation
LOAD FAILED: Press [] button...

So (as tumblep was bootleg1) I also included tumblep2 which was bootleg 2 in the same rom folder and tried running the emulator but it throws the same error, o top of this I have tried to run it in 1.50 kernel but still the same error. Any help or ideas please?

Is it not compatible with 5.00?

Thanks
