Re: Uzebox inside an FPGA ?
I've been trying to learn more about FPGA's off an on for a few years new. The NEXYS2 system is pretty cheap (around $100) and there are other ones even cheaper than that. See http://www.digilentinc.com/. For some decent books on basic FPGA development that are ready to run on the NEXYS2, see http:/...

Re: Emulator Patch Submissions
You'd need to dig up a unix patch utility to apply it, or just stare at the line numbers and do it by hand. + in the left hand margin means add a line, - means delete.

Re: Emulator Debugging Output (printf-style)
Nice one! I've done temporary hacks to print out access to particular ports for numeric debug spew, never made anything as nice as this.

Re: Emulator performance on GNU/Linux
That loop is a little misleading -- all it's used for is to generate the "emulated frame rate" display you see updated once every several seconds. I pretty much count on the underlying SDL implementation to magically sleep on a flip or a full audio queue. I'm not an SDL expert -- I added s...

Re: Im gettjng a Segfault
gdb a.out (or whatever you called the resulting executable)
run whatever.hex
bt
Paste the results here.
Also, run it with no parameters to see the options it supports, and try some of them to see if they help -- -fullscreen, -nodoublebuf, etc.

Re: Sound is Messed up Under Linux
SDL is a major timesuck under MacOS as least, wouldn't surprise me if it was the bottleneck on your setup too. I used to spend a lot of time in Linux ten plus years ago, back then there were console VGA modes available -- maybe one of those would be faster? (A 3Ghz machine should definitely be fast ...

Re: MMC/SD Card Emulation?
One of my first posts on this group last November or so included some code that would do low-level physical reads of an SD card under Win32.

Re: Emulator performance on GNU/Linux
On MacOS at least, SDL performance is fairly terrible. If you want to see how fast the emulator can run, turn off sound (-nosound I think) -- otherwise it slows down emulation to avoid flooding the sound buffer. If/when particular video modes become dominant, it would be pretty simple to detect the ...
