NEO4ALL/AES alpha-preview coming soon !

as always- i stand correctead.


but hey, quzar, you should see if anyone from dciberia might co-op upgrade the tg16 emu with you, and like, make like a superhero coder crew.

If you have it start up by loading only the files (since neogeo games are split into one file per rom chip) that are being read at that moment, then unloading the ones that were not used in a long time and loading in ones that are being requested, it would give you a lot of slowdown (while reading disc) everytime you need to load in a new rom. Basically this will only work for games where data is stored in clumps based on what level you are in
I'm not sure how chui is doing it, but if it is a per-file basis, it might not work as well as if he would have lets say, just 256kb chuncks of files...

It is not true, all roms are out of order, so appropriate prefetch is the key. After, game working-set is not very large (game depend), i think that some games won't be playables because large working-set and you will have to play without sound for cut out working-set.
Also, for playing to NEO4ALL/AES, you will need convert NEOGEO rom first to correct format.
I made a rom converter program for Windows and GNU/Linux, this program will have a little prefetch map database for each game.

Did you try MMU with KOS? Only can simple map memory and it is not enough.
I had to patch KOS for work store queues and direct render, also i captured real SH4 exceptions for speed up.

Dreamcast never can emulate n64 properly, it is not possible.
About gba, Dreamcast emulator could be possible if we could run gba ARM code under Dreamcast ARM capturing exceptions and mapping SRAM .. and i don't know if this is possible.

I have tried the mmu in kos. I know how I would use it if I were to make a system to use large roms, and it could also be done in software, with very little speed loss as the big loss will come when you are reading files off disc, to which the few ms you save won't make much difference.

Rand Linden thought N64 emulation on the dreamcast was possible, and he knows the dreamcast much better than anyone out there.

It is probably possible to run arm code on the Dreamcast's arm, BUT it is a lower version than the gba's and does not support thumb code, so it is not possible to directly run gba code on it.

wonderfull, chui you are the man !

That's right : UNBELIEVABLE !!! Nice work, i'm waiting for this version !!! :D

prefetch maps = the future. (maybe for more than 1 system, i hope)
Hey Chui, yeah! this means with people making prefetch maps, to like thier vmu, maybe via a little speed reader to chuck into vmu, then upload to the web, we could have prefetch databases for lots of stuff, eh chui??? or is such a thing possible, or worthwhile, or should we have a program on PC to get the data, and upload it to you via a central thingy??? sound good?
would this help with Intellivision and MESS type stuff?

WOwww!!! This is simply wonderful!!
I've never thought something like that could be released, that's so amazing!!
Thank you for your work this is so great !!! ;)

you are misunderstanding the use of the technology. This can only be used to do two things: 1)map large virtual files with hooks to load parts of them and 2) remapping addresses to get slightly faster and slightly lower level emulation.

i have no clue at all. not just in video games, technology, etc.... but also people skills, and tons more.

im a terminal dumbass.

Obelisk, no need to feel like a dumb person you know, everyone is good at what they're good at. And anyway any improvement is a good thing, and it all depends about using the technology properly to get it to its fullest use. At least it seems that Chui found a way to use it properly for his stuff, which is nice to hear.
