Re: OVERDRIVE II
http://notaz.gp2x.de/img/hw/megadrive_model1.jpg http://notaz.gp2x.de/img/hw/megadrive_model1_case_back.jpg (with MED + both addons attached) Just like the demo itself warns, some plane glitches on "where is she" and few other scenes. Other than that, really enjoyable demo, much appreciated! Thanks ...

Re: Networked Genesis hardware
I don't think this can work, the machines will desync eventually because of oscillator variations and no game hacks will be able to compensate it. There is also a problem of not fully defined state the machines start in and you'll get a desync at the very start of the game.

Well even expansion port can't do it, SegaCD has to get away without interrupts to MD's 68k. You are partially right about Z80, partially because it only works in master system mode (one of address lines is then repurposed for Z80 NMI). The only things I can think of is connecting a wire to one of I...

How does the Everdrive work for this case exactly? Maybe by watching address bus and toggling CART_IN during BIOS access? Isn't it the case when a cart is inserted the CD BIOS (the original one in the Mega-CD) gets mapped to 0x40000000 and cart is mapped to 0x00000000 and this swaps around when car...

Sonic romhacks playing themselves to completion
These are currently fastest Sonic TASes (tool-assisted speedruns) hacked into the ROMs themselves and resynced to play on real hardware.
