NEO4ALL/AES alpha-preview coming soon !

[chui]

NEO4ALL/AES is a NEO4ALL fork using MMU for load large NEOGEO home console roms.

Yesterday, Fox68k and me tested first playable pre-alpha version and Metal Slug X (64MB rom) is very playable !!!! Theoretically, 298 games will be supported.

A few days, i hope release a alpha-preview for testing everybody.

o_o oh my goooooooooooddddd !!!!!!!!!!!!!!!!!!!

=D BEAUTIFULL!!!!!

Chiu i made a list of compatibility =D WHEN put the release.
Great news *_*.
I hope of play KIZUNA ENCOUNTER too much beauty.

Wow, and I had just gotten MVS code running a bit ago too. I hadn't thought to use the mmu in such a fashion though, I'll have to see how you do it when it get's released, although this being a fork won't be good for it.

You most definetly mean MVS and not AES as there does not exist a proper AES emulator out there (look at your code, if you have pd4990 emulation, it's not AES )

My mmu_file/mmu_handle library will be LGPL, you will can use if you want it.

About AES, only it's a name but will need 'aes-bios.bin' for working, and it emulate home version, so no insert-coint but select button.

i see the list, but i don't uderstand you have tried all the games and work in the emu?

[DARKGATE]

Great QUZAR i wait also you news , you neo geo emu, and pc-engine =).

What's MMU? If you loaded a rom that big is it possible to apply the same logic to emulate other systems with large storage media?

[quzar]

MMU stands for Memory Management Unit. What it does is allows the user to set up a memory map of up to (iirc) 512mb that can consist of virtual memory addresses. If one of the virtual memory addresses is called, then it can trigger a fnction to load the actual data into memory.

In theory it can be used like this, and I proposed such ability of usage for emulation a while ago on dcemulation, but there isn't much gain in doing so compared to a completely software version of the same thing (using queues to determine what is loaded into memory and such) and there is a high chance for mapped spaces to accidentally clash with the rest of the program.

MMU hardware is memory management unit, allows and manages virtual memory, so NEO4ALL/AES loads rom on demand.

It is hard to use it, but my final university project was a micro-kernel and uses MMU.

With Metal Slug X (64MBytes rom) can see that working-set for first game stage is 7040 KBytes, so only you need 7-8 MBytes for playing first state.

The key is prefetch and page-fail algorithms for minimal and fast loads.

Unbelievable! We will soon be able to play games that nobody would have imagined would be seen on dreamcast.
