I really want to play dreamcast on portable system, will the dc emulator appear on pandora, i've heard nulldc is getting ported to pandora.

Is a Pandora app really to be considered homebrew? We don't call secret Maryo chronicles a homebrew.CC_machine said:maybe some time in future. not all games will be playable, most likely.
nulldc will most likely be very optimised for the PSP, though...
and not soon, either. don't hold your breath. enjoy amiga, MAME, PSX, GBA, SNES etc and HOMEBREW! like the rest of us ^^
After the code is cleaned up/rewriten there are plans to port to pandora ( www.openpandora.org, realy cool stuff ) and possibly other consoles (wii seems like a nice target, ps3 if theres a way to get 3D access). ALL THIS MAY(OR MAY NOT) COME AFTER THE CODE IS REWRITEN, SO DONT ASK ABOUT IT NOW(you’l just waste your time, realy). The code will be open sourced as soon as it gets stable.
mkinzler said:But SH-4 is much more powerfull then ARM and additionally you have to do do the soundcode. Let's wait and see.
At first I thought you were mistaken, so I've read that SH-4 does 360MIPS@200MHz (1.8 iop/clock) 1.4GFLOPS (3.89 fop/clock), browsed through ISA reference and I must say - it's a very good & efficient CPU.mkinzler said:When you compare it in relation with processor speed. The cortex has a higher clock but is it enough?

It seems that interpreter-based emulation on OMAP is out of the question and recompilation/just in time compilation is a must.
Dreamcast was in fact a beast.
