I made a new release FSB131020.
This time the changes are very little, in fact I just fixed one self-made bug in the sprite collision detection.
Now the original code is active again and games like Archon will work properly.

All former feature are included as well :)

Info for coder/porter:
Changes are in "Denise.v" file only. Sources are included in the archive.

Great! Thanks, Boing4000!
It's nice to see the Minimig is still getting love. I come here almost every day, because it's the computer I use the most after my Linux machines.

Same here.
Minimig has become my favorite Amiga and I will keep it up-to-date as good as possible :)

Great work as always.
I realised that my minimig crashes in turbo mode when using the 49 mhz core. But it seems to run stable in 42 mhz turbo mode.
This seemed to happen first when using my new arm board with spi mod. There never was a problem with the old PIC in Turbo, regardless wich core i used.
Now after using 42 mhz core and setting maxtransfer to 0x1fe00 everything seems to work fine.
I´m just curious if this is normal behavior.

The standard MaxTransfer value could be the reason for a system crash.
Older PIC firmware do not take care of this parameter, only new (ARM) firmware act on it and any file read >128KB in size can show bit-error. So also program/binary files could crash after load into RAM.
A MaxTransfer of 0x1FE00 is always save. Only NATIVE SCSI device are able to handle larger value.

Most likely the Turbo mode increased this effect in combination with the CPU cache.

Thanks boing4000
Any correction of errors is good for Minimig.
Unfortunately, my Minimig is broken, hopefully will be fixed soon ....

Oh, what happened to the system?

Boing4000:

An historic feature request: could we have joystick emulation configured to use arrow keys + left ctrl + left alt instead of the numeric pad, pretty please? :oops:

I will see if this is possible.
Actually the numpad was selected because it can be switched into 2 modes (numlock on/off).
The cursor keys are permanently available for the Amiga-side and this may cause conflicts in handling.

Would it be OK for you if I relocate the prime fire (KP 0) key to another one, say right CTRL or left WIN key?

Thanks for taking the idea into consideration, Boing!

Left Win key is ok for me. Right CTRL is too close of my other hand and that's not comfortable at all.
This "virtual" Joystick could also be activated and deactivated using the same numlock key (same as now), but using the arrows + left WIN + left ALT, for example.
