MAMEWorld Forums - MAME Artwork: Official - Re: Microvision Artwork

This was one of the handheld game systems that had along with assortment of 1970s era Mattel led games back in late 1970s.

It should eventually be supported, but unsure when.

Viewing code in source file, it is a hash file based handheld because cartridges are changeable compared to dedicated single use handheld game systems.

Since my out-of-date computer is unable to run versions of MAME newer than .180, I won’t be able to help out since the softlist hash file UI is on versions of MAME far newer than what my computer can handle.

The most similar setup artwork-wise is Nintendo Game Boy system. I believe the hash list file for Game Boy has it were users can run the handheld Game Boy system without having to exit MAME if selecting a different supported game cartridge. I am uncertain if there is any artwork that is supported for Game Boy system at this time. Maybe there is. I am not sure if it is in a dynamic state in which if a cartridge uses a specific bezel component and if it is possible to have each cartridge with its own specific artwork able to be changed when switching to a different game cartridge. Thanks with doing the artwork support for the cartridges used with Microvision system.

Somebody else should be able to provide exact needed answer(s) sometime later.
