Everyone's favorite SMS/GG/Colecovision/SG1000/SC3000 emulator has been updated! Changes:
Meka 0.65
---------
- Rewrote palette system in the attempt of reducing palette changes
even more. As some people noticed, on some computer, the Windows
version had terrible slowdown and incorrect colors at some occasion
and especially in Game Gear games.
This is due to some DirectX video drivers which force waiting for
a screen refresh before each palette change. Problem is that some
drivers does that and some other do not. Palette changes in MEKA
are now better grouped so that the wait should not affect gameplay
in most cases.
Please report if you notice any palette related problem in this version.
Windows users, note that you can still get color flickering in some
video modes. But overally, things should be much better.
- Rewrote hardware sprite collision emulation for video modes 1, 2 and 3
(used by SG-1000/SC-3000/SF-7000/Coleco Vision software, mainly).
Sprite collision are now processed line per line, for a very accurate
result - at the cost of a slighty slower emulation. Although machines
using those video modes usually can't poll for the current line, some
software can manually do a similar job, making this precise value useful.
This fixes "Froggy" and "Gold Miner" (SF-7000), and maybe more.
Please report if you notice any collision related problem in this version.
- Fixed SMS/GG scanline counter to return accurate values.
- PAL/SECAM modes now have 313 lines instead of 312.
- Fixed "Daffy Duck in Hollywood" (SMS) which in some cases had
incorrect scrolling on the level score screen.
- Fixed palette switching in "F-16 Fighter" / "F-16 Fighting Falcon",
colors were incorrect during one single frame after the title screen.
This bug was introduced in a previous release.
- [Windows] Fixed screen capture (did crash with some DirectX drivers
in version 0.64c).
- Added Chinese flag in the file loader and associated the early dump
of Hokuto no Ken with it.
- Added and modified entries in the checksum and compatibility lists.
Fixed a few inconsistent entries.
Some particular renaming includes:
Chase H.Q. --> Taito Chase H.Q. (official name)
Story of Mio --> Hoshi Wo Sagashite... (official name)
Hokuto no Ken [B] --> Hokuto no Ken
Hokuto no Ken [A] --> Hokuto no Ken [China]
- Updated documentation.
- [UN*X] Released a quick & dirty GNU/Linux build, codenamed "MEKANIX".
It is not perfect and I do not plan to completely support it, but I hope
it can be useful to some people (some asked for it).
Please read MEKANIX.TXT if you want to use it.
