Makaron Test 10 - 模擬器

http://dknute.livejournal.com/

I think I′ve finally got the DMA code working. Well, for me at least It
needs to be tested further on variety of hardware - and that′s where you
people come in. Expect T10 soon.

Some loose thoughts I feel like voicing:

1) T10 might be a bit slower than T9 series. It′ll most likely affect only
low-end systems as there isn′t really much of a difference (if any) on my
E6600.
2) WinCE games usually crash when emulation speed drops below certain
treshold. In other words, if you got fast system you should get stable
performance.
3) Due to changes in GD-DMA code loading times are back. It′s considered
normal behaviour since this is how Dreamcast works. Thanks to those changes
compatibility has improved and following titles should now boot and work:
- all Dream Preview discs
- original MIL-CDs
- Street Fighter Zero 3
- SEGA Tetris Online
- Tetris 4D
4) CD-DA (audio tracks) will play, but still use the older method of fetching
data. This might cause Makaron to crash but it′s very unlikely as data reads
and playing audio are mutualy exclusive tasks.
5) There are some minor changes in full-screen setup code (the debug window
will be hidden and not forcibly refreshed). No 16:x aspect ratios yet.
6) Changes to sorting/drawing code broke shadows in Virtua Fighter 3tb. I′m
not planning on fixing that anytime soon though, as it would break many other
things. Late T9 versions have this problem too, by the way.
7) Makaron now disables screen saver when run. It′s only going to be a
problem if it crashes, as it might not re-enable it on exit. Just so you
know.
If you manually enable MMU the recompiler will not switch to address
translation mode until it′s actually requested, so there′s no speed penalty
in BIOS and most games. Some however (like Ikaruga) use only partial
translation and this can be emulated without full-blown MMU support. It′ll
work either way but will be a lot slower with MMU enabled. Some WinCE games
are automatically recognized (this works only for GD images) and MMU will be
turned on when necessary. In short: keep it off unless Makaron complains
about it.

UPDATE: Few more notes:

There were some last-minute cleanups in the code, I hope I didn′t break
anything
MT version is the one I actively develp, the other is just dumbed down not to
support threading. Not tested much so your mileage may vary.
As always, make sure you backup your own INI files if you want to keep them.
For GDROM.ini though you should comment out the GDMT setting, or choose one
of the following:
-1 is immediate mode. This will block emulator and allow the read to
complete. In short: worst performance, but should always work. This is also
the default mode for non-MT version.
0 is deffered mode. The read still blocks, just not right away but rather
outside SH4 main loop. It might provide smoother emulation (if it works at
all
1 is threaded mode. Disk reads are scheduled to separate thread for another
core/CPU to take care of. Best speed, smooth emulation, should now work with
every game. This is the default for MT version.
Threaded mode can′t be selected for non-MT version of Makaron - deffered
method will be used instead. This limitation was introduced on purpose, and
might be lifted in future. Note that unless you have multiple cores/CPUs it
will work just like deffered mode anyway.

I′d also like to remind you that there′s a frontend to Makaron called
mkfro. Highly recommended for people who can′t work my INI files.

UPDATE2: If you experience random crashes while in-game movies play (or are
about to start), or from time to time CD/GD image refuses to boot (but works
most of the time) - report this. Give me the title and your PC specs.
