Important changes
MESS/MAME has undergone some rare, but important changes in usage that users should be aware of. In particular, when many releases are skipped, things may suddenly appear broken, but there may have been a change a while back.
These changes may require you to modify your existing MAME setup to achieve the same behaviour as before the release.
| Version | Changes |
| 0.229 | The main executable is now called mame(.exe), not mame64(.exe), for all architectures. |
| 0.227 | Reimplemented Horizon RAMdisk may fail to load the older NVRAM file; backup to disk and restore recommended |
| 0.213 | The Geneve/EVPC mouse is unplugged by default; must be explicitly attached to the colorbus. |
| 0.199 | Geneve BIOS must be selected by the switch "-bios x.xx", not by DIP switches |
| 0.199 | GenMod is now a separate machine, not a configuration of the Geneve. Has its own ROM zip file (genmod.zip). |
| 0.186 | The I/O port of the 99/4A is explicitly emulated. Device paths must be prefixed with "ioport" (like -ioport:peb:slot2). |
| 0.174 | ROM dumps are reorganized; requires to use new system ROM zips and cartridges. Older dumps are not accepted anymore. |
| 0.174 | The cartridge type "paged" is replaced by "paged12k" and "paged16k". Requires to replace affected RPKs. |
| 0.165 | The internal 16-bit 32K memory expansion is now off by default. Use the PEB card or turn it on in the OSD. |
| 0.131 | Cartridges are emulated by RPK files. Plain dumps ("cartc.bin", "cartg.bin") are not accepted anymore. |
