Games are loaded from ADF files, disk images, so in turn writing is done to these ADF image files!

Hi, I am curious. How work floppy write since there is no floppy drive?


All the "floppy disks" are stored as ADF files on the SD card.  Originally the Minimig could only read these files (imagine them as floppies with the write protect tab set), but with this new core it can modify the ADF file as if it was a real Amiga writing to a normal floppy disk.  Likewise, you can format these ADF images from within a program in order to create a save game disk.

You can get ADFs of your games by either downloading them from the internet or by making your own from your actually floppy disks using utilities available on Aminet.  The only problem most people will have making their own ADFs on a real Amiga will be how to transfer them to the SD card, but there are various ways to do this.
A2000, A3000, 2 x A1200T, A1200, A4000Tower & Mediator, CD32, VIC-20, C64, C128, C128D, PET 8032, Minimig & ARM, C-One, FPGA Arcade... and AmigaOne X1000.

i would like to see this minimig inside an a500 case connected to the keyboard and extended cables for the joystick ports so they will be mounted where they originally goes, same for the power switch etc etc...

that would be a fun project to see....

I think it does already, just the main sprite (Superfrog) was corrupted, I think this new core addresses that.

I'll let you know, I will update my site soon with all the games working with this new core. :-)

www.loriano.pwp.blueyonder.co.uk

Everything is there :-)

I haven't tested Superfrog, but I've seen the advert for it in Alien Breed SE ;-)

I've updated the Minimig games Wikki, so here's a more complete list of what works:

http://www.opencircuits.com/Minimig_Software_compatibility

Some games are listed several times because they have been tested with different cores.  The ones marked 080408 have been tested or retested using the new core/PIC update.
A2000, A3000, 2 x A1200T, A1200, A4000Tower & Mediator, CD32, VIC-20, C64, C128, C128D, PET 8032, Minimig & ARM, C-One, FPGA Arcade... and AmigaOne X1000.

Very very good work, thank you Jakub!! :-)

But I do have a problem in compiling the source code. ISE 10.1 stops with an error: "Place:1018 - A clock IOB / clock component pair have been found that are not placed at an optimal clock IOB /"

What could it be? I only used the shipped source files.

Superfrog works perfectly, it was the game I most frequently tested. I think you know why  :-D

And it was a pain in the a** to get it working correctly, usage of sprites in this game is really weird (and very similar to other Team17 games) and doesn't conform to description in the AHRM.

There was also an issue with horizontal overscan: when right display window border was set very close to its limit the normally invisible part of the horizontal display window wasn't hidden at all. Project X also had similar problem.

I used Xilinx ISE 9.2i and haven't upgraded yet not to risk compatibility problems. In a few weeks I will upgrade and check why it doesn't compile.

Sound like one that I'll have to try myself.  :-D

Awesome work!

Superfrog is, in my opinion, the best 2D platformer.

Well Done! :-)

Pardon me if I am asking a "dumb" question.  I have looked around but can't find an answer.  Does the minimig run WB 3.9 ??

Sir, I believe that we have a problem with your brain being missing.  -Firefly-

It can use a Kickstart 3.1 ROM and boot to Workbench 3.1, but it cannot run OS3.9 because it is below the minimum specs for OS3.9 and (at the moment) has no hard drive emulation.

Remember that this is a reimplementation of the A500/A500+.
A2000, A3000, 2 x A1200T, A1200, A4000Tower & Mediator, CD32, VIC-20, C64, C128, C128D, PET 8032, Minimig & ARM, C-One, FPGA Arcade... and AmigaOne X1000.

OK where can I download ISE 9.2i? On xilinx.com is nothing to find. But right now I dont need to compile an own core. Its just about 2 things:
- Power-LED should not dim. 'NET "pwrled"  LOC = "P94" | IOSTANDARD = LVCMOS33  | DRIVE = 12  | SLEW = SLOW  | PULLDOWN ;' in Minimig1.ucf
- Switch 7/14MHz CPU Clock (not necessary but funny :-) )

Just for the record, here's the bare minimum requirements for OS3.9:

CD-ROM drive
Hard drive
68020 or higher processor
Amiga 3.1 ROMs (version 40.xx)
6 MB Fast RAM
A2000, A3000, 2 x A1200T, A1200, A4000Tower & Mediator, CD32, VIC-20, C64, C128, C128D, PET 8032, Minimig & ARM, C-One, FPGA Arcade... and AmigaOne X1000.
