I can make mmu file then rebuild aes4all so it looks for the mmu fetch file from a romsdisk no thrashing of the gdrom or gdemu it be super fast
We need help to create prefetch files for NEO4ALL/AES emulator for Dreamcast.
Download package HERE (
http://chui.dcemu.co.uk/releases/neo4all_prefetch.rar) and follow next steps:

HOW TO CREATE INITIAL NEO4ALL/AES PREFETCHS
This is a little guide about how to create initial prefetch files for NEO4ALL/AES emulator. You need a BBA or coders cable for sending prefetch information from Dreamcast to PC.
In next steps, i suppose that you have a BBA, for coders cable is very similar.
1.- Create a normal CD with NEO4ALL directory+files and put your convert ROMS (.AES) to any directory too.
2.- Run DC-TOOL loader tool under Dreamcast.
3.- Swap CD with your prepared CD (step 1).
4.- Go to GNU/Linux or Windows command line and launch binary redirecting standard output, example: 'dc-tool -x aes4all.bin > prefetch'
5.- Choose any ROM without touch emulator params.
6.- Play normally and try to avoid large presentations. When MMU cache will be full emulator will stop itself.
7.- If you had played a lot of time (>30min), go to exit option menu.
8.- Send me prefetch file (stadard output redirect):
[email protected]
9.- Also you can test your prefetch, edit prefech file and cut lines between '_MMU_HANDLE_DUMP_MEMACESS_ -------' and '-------_MMU_HANDLE_DUMP_MEMACESS_', only data without tags ..._MMU_... using wordpad.
10.- Copy cut file as prefetch/name_of_aes.pre under convertneo directory and rebuild .AES file.

I can rebuild the aes4all emulator direct it to load the aes-pre from a romsdisk making it included in memory not need to thrash from the gdrom or sd card it should solve music problems and others fetch file be as fast as main rom can be read at the same time as the rom
