The amazing psp developer StrmnNrmn has hopes for releasing the latest and greatest Nintendo 64 emulator, Daedalus R11 next weekend. He has been working hard the past few weeks and has results to show for it:
* Streamlining the N64-format-to-PSP-format texture conversion process has halved the memory resources required for each texture, StrmnNrmn reports. Slightly faster than the previous approach, too.
* A "very simple one-line change" to the texture cache code makes the cache "100% leak-free" and a surprising 4-5% speedup.
* Last significant change is that he set a hard limit to how much memory the texture cache used. "This change means that if the limit is ever reached, I just display white textures until some texture memory is freed up a little later. Previously Daedalus would just keep allocating RAM until it ran out of memory and crashed, so the new solution is much nicer."
With the changes that he has done, StrmnNrmn says that he "can can permanently allocate 8MB for the Expansion Pak, and not worry about running out of memory(which caused crashes). A welcome side-effect to all the texture changes I've made is an approximate 5-10% speedup over R11." Strmn Nrmn has a bit of work left to do but hopes to release R11 by next weekend.
