Gngeo2x

[locutus]

Hi to all.
I know that this is a little bit off topic, but I think that neocdPSP could be a great starting point for a NEOGEO AES emu.
On this page gp2x-emulation.dcemu.co.uk/gngeo2x.shtml we can find the description of a NEOGEO emu for GP2X that is capable of loading roms that exceed the memory limit of that console (64Mb).
On the readme included in the emu it is stated:

BIG ROM Support:
Gngeo 0.6.7 add Big roms support on the gp2x. The principe is simply to mmap a special dump file and use
it as gfx memory. This file have to be created on your box before.
I'm pleasently surprised by the result. On my modest SD, games like rbff1 are playable. A fast SD is still
recomended
Please note that newer (encrypted) roms support is very limited in gngeo. But some hacked one made for
NeoRageX work.

Here is a little tutorial to enable big rom support (garou, fatal fury realbout, etc.)
- The first things to do is to compile the dumpgfx utilitie for your platform. A version is available for linux. Help is wanted to port it on other platform (especialy MacOS & Windows)
. Untar the dumpgfx.tgz available in the source package of gngeo,
or here m.peponas.free.fr/gngeo/download/dumpgfx.tgz
. go to the dumpgfx dir
. Compilation is a simple "gcc *.c -o dumpgfx -lz"
- Now, Create a dump with "./dumpgfx games.zip" where games.zip is the game you want to dump.
- A .gfx should have been created
- Copy this gfx file in the gngeo's roms dir on your sdcard
- Don't forget to copy the rom too
- Now you can launch the rom as usually, and enjoy.

I think that this technique could be implemented in neocdPSP in order to load AES roms.

Yes but I want to finish the cd part first, I don't want to have to fix bugs everywhere at the same time !
Anyway we are almost done now (I won't emulate the raster effects, at least not for now, I just want to fix the bugs, not to make the perfect neocd emulator !).

I'm just happy that Zelurker is even thinking about tackling AES emulation. Hell if the gp2x can do it then I have no doubts that the PSP is capable of it.

I love playing the Neogeo on my PSP. Everyday on the train to work I boot up a nice game of Metal Slug or Last Blade, it kicks sooooooooo much ass

I'm cool with Zelurker working on fixing the NeoCD bugs because the project is well worth it. If AES emulation follows after that, then I'll truly be in heaven.
