Never mind on the flash part. I got that figured out. All of the following code was written with the ham 2.71 dev kit. This code also needs the MBV2 ...
I haven't seen this concisely placed anywhere else in this list so I'll go ahead and post what I've learned over the last few days going from GCC version 2.95...
Hi GBAList! Experimenting with big composite sprite-based characters, we realized that it was very heavy to render them on the GBA using many rotating parts...
... Yes. ... There might be a couple cycles of "wait states", but you'll usually get far fewer than one per read or write on average. More importantly, GBA...
Hi Ronald I can give you a bit of info on the sprite stuff as I know it. Our engine builds composite sprites all over the place w/o any real slowdown. We...
hello, i wrote parport extension for the linux version of the f2a linker (http://www.emulinks.de/f2a/). would like to ask if somebody wants to test the parport...
... Either that, or cache decompressed cels in EWRAM. ... The GBA expects sprite coordinates on whole number pixel boundaries. Try overlapping the parts of...
On Saturday, November 8, 2003, at 04:57 AM, gbadev@yahoogroups.com ... If it is, in fact, round-off that is causing your error, you can make sure that your...
i would normally just use the following to round while shifting down c = (c + (1<<7)) >> 8; mathematically, this is like 'floor(x + 0.5)', which rounds x to...
"breaking up" of rotated/scaled OBJs is not due to fixed point rounding error, it's due to the unpredictability of the pixels that get lit in the hardware...
... Yeah, we gave a thought about double buffering as a way to avoid the constraint of updating VRAM during vblank only, but (having read Mr. Yerrick's paper)...
Thanks for the replys. Overlapping by 1 pixel is the method we are considering, but it'd be nice to know exactly how the hardware decides where to put each...
... GBA interrupts are IRQ by nature, not FIQ. You can still switch ARM to fast interrupt mode manually using msr, but anyway, real interrupts will never be...
... A 32bit RLE system running out of cpumem in arm can be actually be faster than DMA transfer if enough data gets repeated and is generally not any slower....
There was amiga wizard-converter written by gryzor that might convert future composer module to protracker... (various odd formats were supported, I dont...
It was called pro-wizard and was mainly for converting noise/sound/pro-tracker derivatives back into noise/sound/pro- tracker modules. Future composer is not...
... RLE is in theory a special case of LZSS with a window size of one symbol. The big purported advantage of RLE over LZSS comes only with the larger copy...
While symbol compression is slower, you can offset this quite a bit with just a little buffering. I found that buffering 32-bits of data at a time into 1...
Hi, I'm new around here. I'm using a GBA and I thought I could make more of it. I'd like to build a device which is simply plugged into GBA and has a Slot for...
All the information for how the gba cart port works can be found in the nocash GBATEK document ( http://www.work.de/nocash/gbatek.htm#auxgamepakbus ) Although...
... True, SmartMedia and MMC aren't fast enough to stream cart data at the full bandwidth of the cart bus. However, wouldn't it be possible for a "full game"...
Maybe this has already come up. Why not just make a multiboot device, but one that doesnt require a flash cart. The program(s) are stored on sd or mmc or...
