Portable C64

rkauer · 24 May 2009, 09:55

If this guy made it, then it's just a matter of do the same for a lovely A1200 (or A600) portable!

Linky!

This was floating around a while ago i think (maybe in OT?) Still fantastic, pity he couldn't fit a 5.25" drive bay in it!!

While these are great "museum" collectors pieces. I doubt they are very robust and would stand up to every day usage.

A bit OT here but I have a question. How come the C64 can play MP3 files with MMC64 and MP3@c64 while the Amiga needs at least 030 to use the MP3@c64?

Does the C64 version need additional hardware?

I would bet it is simply because the Amiga app has been compiled with 030 settings?

It is a full MPEG decode in hardware so should not need any more CPU than what it takes to copy the data from RAM to the I/O port.

Yeah, there are solutions that run on a 68000. Probably a compilation "error"?

Hello,

If you want to make your own portable C64 (and Amiga too), you will be able to do it using this card I designed :
http://www.arcaderetrogaming.com/2.html

It plays well a lot of games already, see by yourself:

FrenchShark, Compatibility and development stage of the different cores?

alexh · 15 July 2009, 19:02

The MiniMig v1.1 PCB is more than capable of C64 and there is at least one open source C64 FPGA core. Not sure but I think the author removed the SID code or something and FrenchShark wrote his own replacement?

The hardest thing about porting any core to any FPGA PCB is the disk emulation interface to the SD card. Each PCB is subtly different and most have a co-processor (and code) interfacing to the SD card which also needs to be tweaked.

Also the primary bootloader (the bit that selects the disk/rom image to use) is different, sometimes it is an intermediate FPGA image, sometimes it is C-code on the co-processor, always different.

The C64 works great (still some games do not run) with stereo SIDs and VIC-1541 in VHDL.

When are we going to see a release then?

We want to have to have a production run of the MCC boards for this fall.
We will release some VHDL code at that time.

There were several one-off portable Amiga's. The best being the A600 based Suzanne. The only commercial thing was StarPaws

Hi,

Did you design you board from scratch and use core done by yourself or does you hw and software work has been developed using existing parts found on the internet? (VHDL from 1541 unlimited, minimig etc?)

The HW is completely done by ourselves.
The VHDL is either ours or modules we found on internet.
BTW, I am half way through the Amiga chipset implementation. I am currently working on the Blitter.
This is the most complex part of the chipset. In comparison, the Copper was a breeze.

Hi,

Its an interesting project, how would you define it compared to Commodore one? It seems to me that the goal is quite the same but I may be wrong.

Make up your mind! IS the display odd or even!?

Anyway, "check".
