Quick question, both noise channel and PCM effects are supported simultaneously? Do we have to do anything special to set that up?

Hi Lee,

Yes, noise and PCM will be usable simultaneously when I get to finish the upgrade. I can't say when that will happen though, ever since Maker Faire I got swamped with loads of "real-life" issues. Hopefully in the next few weeks.

I've published the beta 4 in the first post, it adds support for the remaining video modes and fixed a small bug. Only thing left is add the PCM code for the music player. Should come soon... 8-)

FYI, I updated the main post with beta5, probably the last one before the final release.

So this upgrade frees us about 1/8 RAM and a several thousand CPU-cycles? Am I reading that right?

Nice job! 8-)

You've read well... ;) 532 bytes of RAM to be exact plus >5000 cycles freed and the kernel size was reduced by ~150 bytes. 8-)

Is the SD card library part of the kernel? How about that FAT fragmentation support ;)

No, it's more a standalone library. No progress on this front, though I'm wondering of we should just use an existing open source library. I'm pretty sure there's decent ones out there for the AVR.

I fixed the emulator to support beta5+, and a windows binary is available here. However I just found out I screwed up the kernel's sound engine somehow in the latest beta-5 :roll: ...the DonkeyKong intro reflects the issue. Hopefully I will be able to fix this soon...
