La version mensuelle de MAME est disponible à la date prévue, le dernier mercredi du mois. Je rappelle que MAME v0.216 est la dernière version de MAME a avoir une version 32-bit officiellement compilée: pour les possesseurs de processeurs 32-bit, il faudra soit compiler votre version vous même, soit vous tourner vers une version non officielle si quelqu’un décide de prendre la relève. En attendant, voici les changements apportés:
With the end of November in sight, it’s time to check out MAME 0.216! We’ve addressed the reported issues with last month’s bgfx update, and made a whole lot of little improvements to MAME’s internal user interface. In particular, setting up controls should be easier, and several issues affecting macOS users with non-English number format settings have been fixed. Some of the issues caused bad settings to be written to INI files. If you still don’t see the filter list panel on the system selection menu, try removing the ui.ini file.
This month, we’re able to present two unreleased 1970s prototypes from Italian developer Model Racing: their internal code names are Cane and Orbite. With the assistance of former Model Racing employees, the source code was extracted from the original disks. These games are incomplete, but they provide a unique look into early CPU-based arcade development. Game & Watch titles continue to be emulated, with the addition of Mario The Juggler, and the panorama screen Mickey Mouse and Donkey Kong Circus games in this release.
This release brings GameKing emulation to MAME. The system-on-a-chip used in this low-cost, low-resolution hand-held console from the early 2000s has been identified and emulated. Games for the colour-screen GameKing III are also playable. Acorn BBC Micro emulation has been re-worked to support internal expansion boards, and a number of additional peripherals are now available. ZX Spectrum emulation has been enhanced with better open bus read behaviour and support for two Miles Gordon Technology peripherals.
