I don’t understand, I have install it like the readme file says and I see it on the psp correct with the Atari icon and music, but when I select it, it’s keeps on saying that the data is corrupt.
Can someone help me pleas… I am new with emulators.

you need to install a custom firmware to be able to run any homebrew, and this one in particular.

[R1Santana]

Thank you for the info…
I think I have to wait now for a new update as I already did update the my firmware to 5.1 :( ....

nice program, got it at psp-hacks, how/where do I get roms for this?

[R1Santana]

I found this one...

http://www.atariage.com/system_items.html?SystemID=7800&ItemTypeID=ROM

it still is not working for me but I hoop you can play some of this site...

AWESOME.

Now every game runs at full speed.

Hey ZX - can the speedups you made to this one be applied to PSP2600? They might solve the slowness problems in Pitfall II.

i'm working on pitfall 2 issue ...

Zx- I noticed one slight bug.

When you run it under 4.01-m33 firmware runnign the 4.01 kernel, if you change the default settings for processor to 333 and save it as a default.set file, and then exit, then next time you start psp7800, the default of 333 doesn't load, and it plays at 222, until you go into the settings menu and load it up.

However - if you play it under the 1.50 kernel, it works fine.

Not a big deal, but a bug.

[zx-81]

it works fine for me ... may be a plugin you have installed ?

[carpy]

You were right it was a plugin.

It was Popsloader. Which doesn't really make any sense, because popsloader doesn't affect the CPU speed. Weird.

[carpy]

Actually - it was CWcheat taht was messing with it. even though I had it "disabled" in the recovery menu, it was loading up anyway. once I removed it, PSP7800 is fine, and I can still run the popsloader plugin.

I was all excited about this system when reading about it years & years ago in the early 80's in I believe Antic or Analog magazine. It went on about the Maria chip. Really sad that they marketed the system so poorly. Years ago I did pick up one at a thrift store. Just because I like the design. It's now great to be able to own the whole catalog of games on the PSP.

Although, in all honestly many of the games for the 7800 aren't so great & it almost seems like the Atari 5200 games had more spirit to them. Still cool to have it on the PSP! Thanks again!

thanks :)
