Mame 191 Released

Relevant links and notes below but the two things about this release that really caught my attention immediately was:

"This release includes an experimental Hitachi SH3 recompiler from frequent contributor David “Haze” Haywood that shows promising performance improvements for Cave CV-1000 emulation, and holds the tantalising possibility of bringing similar gains to systems based on the SH4 in the future (including Sega NAOMI)."

and

"Bug fixes to the Saturn/ST-V emulation will enhance your enjoyment of numerous Sega titles from the ’90s."

While I noticed no immediate and obvious improvements in the few tests I did with any Cave or ST-V games on my system hopefully it does improve someone else's experience with these games. Cave games already ran very well for me and Radiant Silver gun (ST-V) still has speed issues but maybe this is a step towards fixing those in the near future.

MAME 0.191

It’s the end of October, and time for the hotly anticipated MAME 0.191 release. This release includes an experimental Hitachi SH3 recompiler from frequent contributor David “Haze” Haywood that shows promising performance improvements for Cave CV-1000 emulation, and holds the tantalising possibility of bringing similar gains to systems based on the SH4 in the future (including Sega NAOMI). Bug fixes to the Saturn/ST-V emulation will enhance your enjoyment of numerous Sega titles from the ’90s. There have also been some optimisations and improvements to MIPS3 and Voodoo emulation, as used in a number of 3D arcade systems.

For fans of systems more often experienced at home, David Haywood also rewrote most of the Gamate emulation, taking it from mostly broken to (hopefully) best-in-class. We’ve also got some important bug fixes for the Tatung Einstein, the NEC PC-Engine console, and the M6809 CPU used by the Tandy CoCo family (among other things). Three more Tiger handhelds have been added for this release, namely Batman, Judge Dredd, and Swamp Thing. The hard limit of four emulated screens has been lifted, allowing you to plug in more video cards, more serial terminals, or just emulate systems that just have lots of screens.

We’ve got some big updates to the software lists this month, with plenty of Apple II cassettes, RM Nimbus software, and over seventy new PlayStation dumps. BBC Torch floppies and Gamate cartridges are now considered working, and Kiki Inland for Gamate has been added. A number of titles that don’t require a PC/AT have been moved from the IBM 5170 list to the IBM 5150 list. There are also some nice additions to the IBM PC and Fujitsu FM Towns software.

Of course, there are lots more bug fixes and newly dumped versions of emulated games. You can get the source/Windows binaries from the download page and start emulating.

After a little more testing, more specifically the games Deathsmiles and Muchi Muchi Pork comparing it to my 186 install there is definitely a performance gain with the 191 build. With my 186 version while the games ran at 100% for the vast majority of the time there were some frame drops and audio glitches. Compare that to the 191 version which ran at 100% all the time with zero frame drops or audio glitches. Also I noticed that the fast forward feature with the "Insert" key skipped through the boot up rom check much faster in 191 vs 186, I do not know if this was something that is new to 191 or if it was implemented in a prior version.

DoDonPachi DaiFukkatsu was an even bigger improvement in performance, on version 186 I was running around the 80% speed but with 191 it was 100% all the time.
