Re: strange output on blargg tests
The Opus5 demo is definitely exposing some issues. It looks like I have some graphical issues to sort out first. (ship appears many times in the background) Then apparently quite a bit of other work too as the background is scrolling (oddly) non-stop. Definitely going to work on a debugger first tho...

strange output on blargg tests
Hi all, I'm getting some bizarre output running the individual roms for blargg's cpu tests. At the end of the test run when (I assume) all the tests pass, I get output like: Passed Failed #10L http://i.imgur.com/7LHoPjN.png Any ideas what might be causing it? Also, running the full cpu_tests.gb rom ...

Re: graphics conversion tools
I threw together a little script (also python) to run all the other scripts in one pass. Link here: https://gist.github.com/jtrinklein/2d8bb6dbf8ac15daa347 also, I had a problem with the scripts. It appears that from PIL import Image doesn't work on all installations. Mine only worked when I changed...

Re: [Q]Is an Arduino powerful enough to fully emulate an MBC
Exactly what I mean by overkill in all the wrong places. A RPi could easily emulate the entire GB, but I'm not sure if the GPIO latency could support emulating the MBC chips, for the same reason as with the Arduino, except with the added abstraction and overhead of an entire OS. I was thinking abou...

Blargg Test 'POP AF' in '01 - special' logic question
Hi, I have a question about the logic in one of the blargg's tests in 01 - special. Test #5: POP AF has some logic that I don't quite understand. First let's look at the source for that test: LD BC,$1200 ;start with BC=$1200 - PUSH BC ; save bc on the stack POP AF ; pop the stack into af (effectivel...
