Megadrive: DGen/SDL v1.28 :: AEP Emulation Page - Emulation News

v1.28 <- v1.27

ROM loader can now use libarchive when available for decompression. This replaces the previous system()-based implementation.
"tobin" has been renamed "dgen_tobin" and no longer has dependencies on SDL and other unnecessary libraries.
CZ80: fixed emulation bug ("weird sound") introduced just before the 1.27 release.
Improved CZ80/MZ80 switching.
Improved save file handling. Z80 context and other important things are now stored. The format is mostly compatible with Gens v5 and save states can be exchanged between both emulators. Old save files are still supported.
YM2612: upgraded from version 0.35f to 1.4b, as found in Final Burn Alpha.
Sound quality has improved as a result.
Improved sound buffer management again, a single buffer is now used with both channels instead of two separate buffers.
Removed 8-bit sound output format since it was useless and annoying to support with the new buffer.
Removed superfluous window resizing messages.
Game Genie codes can now be entered while in stopped mode to avoid crashes when more than one is needed at once. Also, DGen now supports RAM patching.
Corrected clock frequencies for YM2612 and SN76496, sound is pitched a bit higher than before.
Added region selection command-line option. This option reuses "-R" (realtime priority). In case this option isn´t given, the default region used by DGen is now the first found in the ROM header. This option has no effect on PAL (50Hz) mode which needs to be enabled separately.
OpenGL: a single OpenGL texture (and subtexture) is now used instead of two smaller ones, thus removing some of the complexity.
Usual batch of miscellaneous bugfixes.
