The format of the cheats database differs (ascii in 0.124 vs. One database cannot satisfy both these app versions. And app v0.124 is very slow at parsing the cheats db, many seconds wasted every time any game launches with cheating possible.Ībility to use cheats database is broken in MAME OS X v0.135 and Release Notes fails to describe the necessary work being put in. When I moved from old MacMAME 0.103 into this MAME OS X 0.124 around 10% of my ROMs collection needed updating.
I did each one manually myself, and the nice result was my one ROM library can be used in both apps 0.124 and 0.103 - next when I moved from 0.124 to 0.135 an additional 20% of my ROMs needed updating, including the entire NeoGeo series. I found that half the bad ROM files only needed renaming. v0.124 had restricted filenames to 8 chr, v0.135 introduced allowing 9 or more chr. Typically the ROMs needing to be renamed are 8 chr clones of 8 chr parents, especially when the 8 chr results ended up being out of alphabetical order, and its new 9 chr name puts them in order. Down to 10% ROMs needing help, i found that half again the bad ROMs were easy to fix by just replacing that one NeoGeo bios file. The leftover 5% I repaired individually manually, and now I am running every title in a 230 ROM collection from within MacMAME 0.103 (the highest version for OSX Jaguar), MAME OS X 0.124 & MAME OS X 0.135.
The first-only time either of these run, I see an endless waiting progressbar. Quitting and relaunching always puts a stop to that (see also the menu MAME OS X > Preferences > General > Check for updates at startup).ĭL #3 is cheats database v0.126 the highest cheats file that plugs in to this app v0.124 but cannot be used with app v0.135. to use it, unzip and put the "cheats.dat" file into your ~home/Library/Application Support/MAME OS X/ and then tick menu MAME OS X > Preferences > General > Enable cheatĭL #4 is Neo-Geo plugin for v0.124 (and older).
This is the same file found on the MacMAME page.��L #5 is Neo-Geo plugin for v0.135 (and newer including the latest as of writing this). Backup and remove any other "neogeo.zip" file in your ROMs folder rename this file to become "neogeo.zip" in your ROMs folder. Often when a NeoGeo game ROM faults upon moving from one MAME version to another, the ROM can be repaired without downloading a new one (because passing the checksum test means a repair was successful).
