2006-07-11 Thread Blue Swirl
I'm fairly surprised user emulation works at all for 64-bit targets. I'm fairly sure that code isn't even remotely 64-bit safe. On a 32-bit host, a write() from 64-bit program succeeds because the data happens to lie below 4G. I don't know if this can be guaranteed in every case, but then syst

I'm not sure about LZMA, but I'd really like to see this experiment done with LZO. The compression/decompression speeds of LZO are fantastic, and I really don't care to shave off every bit of compressible information as long as it doesn't impact performance as hard as cqcow does. There will natur

I know this is a lot different than the discussion so far, but has anyone considered keeping SDL and using an SDL GUI similar to ZSNES? Take a look (for those not familiar) at http://www.zsnes.com and grab a download. Many Linux distro package managers have it also. You don't need a SNES ROM

ok, I did this experiment (long and painful). a XP2003/SP1 qemu guest required 964,231,168 bytes qcow image. zlib qcow image became 459,686,368 bytes. lzma estimation (4k clusters) is 437,038,838 bytes. Yes, 5% are still gained, but the time to get the lzma'ed qcow is disastrous (especially on s
