VBA is too slow for OMAP3530, ports to Pandora also confirm that. For right now you're better off waiting for a port of gpSP instead (but I'm not going to be doing one).

Yes, if you're willing to invite all of the challenges associated with dynamic recompilers, like dealing with self-modifying code and branches.

The projection effect is accomplished by changing the affine transformation step values throughout the frame, up to every scanline. This ...

Dual core Atoms are plenty powerful enough to run VBA...

Are you trying to save on power consumption? My gut feeling tells me that you'd be better off not using a core at all than using both at full CPU with a lower clock speed. I could of course be dead wrong, I have seen platforms that consume much less power at lower clock speeds than while halting ...

GBA games read from and write to messed up places all the time. It's the result of sloppy buggy coding and a lack of memory protection on the GBA to tell them that they screwed up. A majority of it probably occurs from accidentally using uninitialized or NULL pointers.

If you want anyone to read expanded code I suggest you run it through some kind of formatting tool like indent. Macros suck because they're single line, so expansions contain a bunch of really long lines [img]<fileStore.core_Emoticons>/emoticons/unsure.png[/img]/emoticons/unsure@2x.png 2x" width="20 ...

Neat information. I remember when I was looking at the performance of this game, if you let the GBA execute 1 instruction every cycle (never going to happen on a real GBA) until an idle loop or halt SWI, then what you see is one frame where it uses the CPU full stop, then one or two (can't remember ...

Yes, you can usually use the compiler to do it. If you have gcc try this:

Â

gcc file.c -E -o file_expanded.c

It won't matter if the file is actually C/C++, so long as its preprocessor directives are valid.
