"dumped", in English, has many meanings:

  • Discarded, thrown away.
  • Dumped by your partner = no longer your partner.
  • To take a backup of software or data.
  • To use the toilet!!!! :o

I think Tobias means that he got rid of all his MD cartridges.

Cheers,
Norm.


ok ;)

I have done a disassembly of the QL version. The dump that was posted here has a problem in the data file seg_aaa

I was trying to find where the program accesses that part of the seg_aaa file that is corrupted. So I could try to find what was going wrong.

I was getting close, It seems to be in the middle of a recursive routine, that not only calls itself. But also calls routines that call the recursive routine.

As another copy of the program has surfaced, I have put it on hold. If this other copy is posted here I will try to use it to fix the broken one.


If I will find another one I will send to all here, is a promise.

Could a software blitter routine be fast enough to perform the block transfer of data in parallel with the CPU operation?

The Minerva fast memory move vector could probably achieve this. Assuming the routine could be multitasked.


Strange because I had it on my 1040 SFTM (that haven't the blittter) and works well ;)

So I think It was programmed for use it on a Blitter ST (MEGA ones) but also with others than haven't it (520ST, 520SFT, 520STFM, 1040STF, 1040STFM).

I remeber that when there was many "sprites" on the game is slows a lot.

For the sake of completeness, I attach the zip file containing the only mode 8 version which has been found - unfortunately, it soon crashes and so you can only explore the first screen.
