This prefetch does not work in practice. we already have gdemu and ide could be powered by MVSPSP for dreamcast.


If you have pre built into the bin file it does not use the gdrom to read it so 100% fullspeed pre prefetching

Only why it dont work well is it's reading the rom at the same time from the same drive.. having it in ramdisk it does not and read the rom with out stopping your going to like it when i release it

Pre and emulator are held in memory only read once so gdrom or cdr can just read the rom no blocking like you see now

Works perfect in practice chui included them on the same drive yet he had the src being able to do what I'm talking about you just have rebuild the emulator include the pre in the romsdisk and done..

reading pre from the same disk is never going to work.. it will stop start cant stream 2 files at once

In theory everything works but in practice it never worked!

Yes i know but it will now it was blocking reading off the same image .. what i just told you solves that problem..

well yes but it can and does with a simple re compile and including them off the iso and in the bin file held in a ramdisk there is no blocking and it's faster then reading off a gdemu or ide

This prefetch does not work in practice. We already have gdemu and ide we need to create another MVS emulator.


Anything that means advance to Dreamcast is better than use old methods
