Sega megadrive#Technical specifications
 * CPU: 68000 @ 7.61 MHz + Z80 @ 3.58 MHz
 * RAM: 138 kB total
 * Video: Yamaha YM7101 (seems pale compared even to a VIC-II)
 * Sound: YM2612 5-channel FM and 1-channel FM/PCM, SN76489 4-channel Programmable Sound Generator
 * Cartridge via serialized interface.

Yeah it seems doable. If someone actually get inclined enough to do it is another matter.

With FPGAgen it should be a piece of cake to port to FPGA Replay etc.

Diselmotor + generator = mains supply @ 230 V ;)

I guess tools = Amiga 4000T :P

LOL.  I've alreday mentioned generators and even hand saws to them, but all I get is blank looks.  :D


Better put the power generator in the bushes and tell them "electricity fixed - look wall socket!" :D

Where did you get the idea that I have cleared land at all?

Anyway real estate pricing tend to be in parity with job oppertunities so it's usually the same more or less when considering the quota between living cost vs salary.

I saw the Genlock thread and came to think of what would be needed to make that possible with the FPGA Replay ;)

The right question to ask is if the sallary in the big city is high enough to offset the higher living cost ..?

Why does it need an update?

Ie it works but you wish for bugs to go away and new screen modes to appear. But you don't need them :P

Btw, isn't there a few people with access to the source code that can work out these bugs while Mikej deals with his move?

I think the hugest hurdles are:
 * Motorola 68EC020 @ 14 MHz
 * AGA graphics

But there is both an 68030-alike CPU- and AGA-core. It's an A1200 more or less. That leaves the CD emulation. But that is likely easier than the existing harddisc emulation.

So it's very likely doable, but I don't think there exist any code for this setup. But reconfiguration of existing code and adding CD-emulation should do it.
