NEO4ALL/AES Prefetchs

[M Dash]

Here's my wishlist:

1. and above all: Sengoku 3 (my favorite NeoGeo game!)
2. Nightmare In The Dark (Prototype)
3. Shock Troopers 2
4. Prehistoric Isle 2
5. Strikers 1945 Plus

...well, and of course another Metal Slug is always welcome

Chui, regarding SNK vs Capcom - wouldn't it possible to improve the prefetch so the emulator would know exactly which character's graphics and sounds to load once you selected your character ?
Do you think something like this would be possible ?

I mean the game really runs fullspeed for me but the loading times during the 1st Round still is annoying.

SNK vs Capcom to me really is the most important reason to worship this emulator: Thank you so much for finally bringing this game home to the good old DC !

@Everyone that's interested in contributing prefetches:
You can buy a High-Speed USB <-> Dreamcast Coders Cable for 50 bucks!

AMEN TO THAT!

Would it be better if I created some prefetches with the sound disabled so it doesn't cache the sound so more animations can be cached or dosn't it work that way.

[Christuserloeser]

Yeah, just leave out the .mod file - ...or do you mean the actual emulated sound ?

Hm, personally I prefer to have sound emulated... but I dunno, it depends on the game, a 1:1 vs fighter probably would be fun even without sound...

Sengoku3 & shumps in general should have sound I think...

[Lain]

yeah I was talking about the emulated sound.
I have been experimenting with just turning the sound off in the emu options before making a prefetch but the cache always seems to fill up at the same point as with the sound option on oh well.

I have attached a prefetch (rename to .pre) for kof2003 that I did with the sound on the emu turned off so play with it off

[Christuserloeser]

o_O Very very cool! Thanks a bunch! I'll definitly give this a shot once I got a free second.

Now that you got some expierence with this, would you say it's possible to improve an already existing prefetch ? Do think there might be little room for improvements, if any - or could there possibly even be a lot room for improvements to an existing prefetch ? Like, say in SNK vs Capcom ?

May I ask you for Sengoku 3 ?



Just to be sure: I assume you already know that it's recommend to exclude the AES.MOD and the *.WAVs in your /Neo4ALL/ folder to save some valuable KBytes of DC RAM ?

W00t!!! KoF 2003 Prefetch!!!! THANKS A BUNCH MEN!!!!
*Trying out...*

*Try'ed out*

... *didn't work...*

Just one thing... For WHAT rom of KOF is this PRE file??? oO;

kof2003a
kof2003b
kof2003
kof2003c

Encrypted - Decrypted

Wich one plz!!!!

[Lain]

this one

[Lain]

dang I rebuilt the .aes with the .pre that I made for kof2003 and it didn't work for me , mabey I did something wrong (tho my other prefetches that I made and tested worked)

Chui do you see any major fails in this:

I have all the files you have, but your P1 file is diferent from mine. Your P1 file true name is 271-p1d -> Fully Decrypted

I Have the 271-p1.bin CRC: 92ED6EE3

still, it's the only one diferent... if you could pass me that P1 of yours, i would be very gratefull
tnx in advance

[M Dash]

OK, so here's detailed to how to do it and how it works.
First, you will need this ROM setup:



Then, you will need the kof2003.pre file.
DOWNLOAD HERE THE KOF2003.PRE FILE!

You will need the converter program as well (of course!).

ALSO, you WILL need this modified ROMRC file.
Only the entries of the needed KoF 2003 rom were changed.
DOWNLOAD THE ROMRC FILE HERE!

SO now that you have the converter, the ROMRC file, the PRE file, and the needed ROM correctly setted up, it's time to convert.

Put the ROM file AND the ROMRC file in the same folder has the converter program and insert the PRE file in the prefetch directory of the converter program.

Then, all you have to do, is convert the rom. After converting it will leave you a .AES file and a log file, with detailed info about the convertion. IF you want to check if the file was correctly converted, simply open this log file in the notepad, and check if somewhere around the file says "WITHOUT PREFETCH!". IF this message appears, your rom was NOT correctly converted. IF it doesn't appear, then it's OK!

Now with the KoF2003 ROM converted, just burn it to a simple CD, like any normal CD.

Insert the Neo4All/AES emulator in the DC, run it, and in the options screen of the emulator, switch cds. Wait a bit for the Dreamcast to read the cd, and then select the kof2003 AES file, and run the emulator! It's DONE!

The game runs GREAT and WITH SOUND!, but it needs a little remodeling of the prefetch. IT still has some bugs in the sound, and a LOT of loadings in Mid-Game. Still: it's VERY playlable! ;D

Very special Tnx to Lain that made this possible!
TNX A LOT!

Hope this little tutorial help anyone out!
Over and Out!
