Title: Connecting a JCM Bill Validator to a Windows PC running MK6 Emulator
Post by: Radmaggot on July 14, 2021, 04:37:22 PM
Hi,

I have an Stargames machine running a Windows PC MK6 emulator and I have the buttons and a few other bits and pieces working fine at the moment. I would love to try and get the JCM Bill Validator connected to the PC so it can accept credits via the bill Validator. Has anyone successfully done this or is it even possible? Thank you.

It's most likely not possible unless the program was rewritten from scratch, AFAIK the emulator doesn't have any code for external stuff, and just about everything was patched out - it doesn't even emulate the system base where the machine normally shows the POST/checksums before booting, it just goes straight to the game itself e.g. Found 1 video chip / loading resources.

MK6Emu is not a proper emulator, it was just a test program designed to quickly show off brand new games to the government and/or gaming companies without having to burn chips and set up a machine every single time, it's a fluke it even works at all (and for about a third of all NSW games, it doesn't even work anyway because the emulator was made in 2004, and most later games need newer system code which version 12 (which is hard coded and x86-ified into MK6Emu and probably can't load an original system EPROM set with SH-4 code like it does with the games) can't handle e.g. More Chilli). Until people figure out how to properly emulate this system using a proper emulator (e.g. via MAME or maybe a fork of Demul), no-one will ever be able to properly run MK6 games without a real machine.

In fact, it's probably easier at this point to emulate a Stargames PC3/PC4 or Aristocrat MK7, although "emulate" might be too strong of a word - it would be more like the hacky HLE approach of the 1990s PS1/N64 emulators (but without the plugins) when trying to emulate a modern P3/P4 era Celeron machine, especially if the machines absolutely require a certain BIOS chip and video card and won't just run in any old PC.
