Still looking to buy myself a minimig. What is really the differences between the 2MB and 4 MB Versions?
Can I just stick With the 2MB Version if I don't plan on buying an arm controller? I plan on running mostly Amiga 500 games.
Any benefits with 4MB? Is it possible to later upgrade to arm with only 2MB?

I think 4MB upgrade is mainly for Whdload gaming. So if you're planning on using floppy (ADF) Amiga500 games, you'll be ok with 2MB.
Even with 2MB and no ARM controller, you can still have a small (40~80MB) HDF loaded with non-whdload installable games wich have many floppies, like Monkey Island, Maniac Mansion, etc. saving you from disk swapping nightmares that real Amiga500 without an HDD are for those games. A LOT of Amiga 500 games are installable even if they don't have an installer, too! And they will work well with 2MB.

@runholen:

P.M. sent.

The 4MB version with the ARM controller is a lot better than the 2MB version with the PIC controller : more speed, more ram for WHDLoad and Workbench 3.1, easier uograding ... :=)

Don't hesitate to take a look at our webshop for more informations : http://amiga.amedia-computer.com

Thanks, Laurent aka Faranheit

For ADF games the 2MB version will do its job.
Most games only need 0.5MB Chip + 0.5MB Slow RAM.
The board will offer:
0.5MB Chip + 1.0MB Slow or
1.0MB Chip + 0.5MB Slow or
1.5MB Chip + NONE Slow

Kickstart always take 0.5MB, no matter if the file is 256KB or 512KB in size.
If you intend to use the ActionReplay (AR3.ROM), additional 0.5MB of S-RAM will be lost for AmigaOS. In this case the 4MB upgrade is a good idea.

Anyway the ARM controller is highly recommended.
Not only due to higher speed, but for better compatibility! Some games do not work with the original PIC chip.

Just wondering - is 4mb enough to run any game in WHDload?

For Some title it is not enough.
I do not use WHDLoad but did some tests of a few games. Those who start will work fine and many can be exit via the assigned Quit-key.
Others also start but can not be exit via Quit-key because a 680x0 CPU is required.

Some did not start and report an exception error requester or complain about too less free memory.
WHD is designed for Amiga model with 68020 up to 68040 CPU with a ton of real (32Bit) Fastmem, at least 2MB of Chipmem and present ECS or AGA chipset (for bugfixing those title).

Minimig in general is designed to work as an vanilla Amiga500 with Floppy drive and some other goodies ;)
Therefor WHDLoad never was a factor while developing.
Focus still is at a good OCS and ADF function.

Thanks that is what I wanted to know. So in other words the best option is to go for the cheapest Minimig board (2mb)?

Does it make more sense to wait for Mist/FPGA Arcade/The new Minimig board from Acube?

It depends on your requirements for the Minimig or any FPGA board.

The V1.1 board is perfect for old OCS games and demos, even 2MB will be just fine for ADFs.
The Arcade Replay board will offer more function as 8MB of Fastram (at $200000) and AGA feature.
Other Minimig portings do offer several other feature and more available core.
I am not informed about any new board design from ACube.

From my point of view the MinimigV1 do all the job and I never want to miss this sweet little thing ;)

The MIST board's Minimig core works quite well with WHDLoad, as does the Chameleon's and the DE1's (though the DE1 has less RAM than the others - the MIST and Chameleon can do 24 meg of Fast RAM.) None of the three can provide AGA features though.
