Interesting.

Try this program

http://amiga.nvg.org/warlock/adf/b/Birk+Sundell/100C64Tunes.adf.gz

It is known to be sensitive to 68000 incompatibility. I dont think it will work, but if it does, then great!

The Hardwired demo times the 68000 multiply instruction and if it is not a time it expects it comes up with: "This demo don't like Axel". (Axel = Accelerator)

This is fantastic!

The unstoppable steamroller that is Minimig rolls on!

Let's see....

If it is Captain Dennis then it is definitely Lieutenant Tobias! :-)

Ha! OPCODE 0x0F0E MOVEP.W .....
My Validator stop here.

Thank You Alexh. Now I can Implement the Movep Instruction.

Do you know a .ADF Source from the hardwired demo?

I have found no program for the AMIGA that use CHK or MOVEP Instructions.

It seems Days of Thunder uses the CHK instruction: http://eab.abime.net/showthread.php?t=1144

@Dennis:
What do you think Minimig2 should contain?

(btw, do you happen to have the appropiate *.ut and *.xst files for Minimig?)

FYI: you can convert DMS to ADF using the xDMS tool

How much are the DE1 boards?  I know that I would be willing to pitch in to get one for Dennis so that the two of you could continue with the collaboration work you have been doing.  If they are not outrageous in price, we could probably get one paid for in donations.

Ok, I just looked it up.  Is this the correct board?

http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=83

If so, it is only $150.  If you (Dennis) and TobiFlex think this is the correct way to go for the MiniMig v2.0, please PM me.
