Une news majeure pour le monde de l’émulation Arcade.


La nouvelle version de ce fantastique bios pour Neogeo/MVS est enfin disponible,
Ce bios, bien qu’à priori destiné au véritable hardware d’arcade, fonctionne également très bien dans les émulateurs, et comporte des fonctionnalités qui vont plus loin que les « simple » cheats, tels que le mode debug, activation du sang… et simple d’utilisation.





Les nouveautés et changements sont les suivants :

New Controller support

Added full four player support to the unibios if relevent hardware detected.
This allows Kizuna to be played in 4 player mode without requiring cheats.
HARDDIP 2 must be ‘ON’ when using MVS hardware, not required for AES.

The AES controller test (2up ABCD) is no longer accessable from MVS hardware
due to lack of exit option, use the hardware test (test mode) instead.

Added a four player controller test which will automatically show in the
standard ‘2up ABCD’ controller test if the four player hardware is detected.

Added a Mahjong controller test which will automatically show in the standard
controller test if a mahjong controller is detected. Press ABCDE on the
mahjong controller to enter test. This code works on either joy1 and joy2.

will jump to the next game regardless due to the way they are programmed.

L’auteur nous informe également que l’on trouve des versions « Fake » de son unibios 3.1 sur Ebay et sur certains forums. Ces versions entrainent des ralentissements pendant le jeu et des resets intempestifs. En bref, RDV sur le site officiel pour acheter la version officielle.


La 3.2 étant disponible moyennant finance, la 3.1 devient téléchargeable gratuitement.

Par ailleurs la 3.1 est à présent ajoutée dans le source de MAME.
