DMA load for standard routines

[Flexmaen]

This is a feature request we discussed in the forum:

Gideon said, that it should be possible to handle standard loading routines via DMA-Load. For example this means a big speed-up for games which have multiple files but do not use any custom loading routine. This also also means that D71-images could be supported as long as standard loading routines are used (which is the most common usecase for 1571-disks anyway).

Is this issue still relevant now we have the custom kernel enabling hyper-speed loading supported by the more recent firmwares? If not, then this issue can can be closed.

I'll test that with the new firmware and report.

Unfortunately the Update from 3.7 to 3.10 bricked my 1541-Ultimate. :( So the report might take I while. I contacted Gideon to see which options I have to make the device work again.

Ok, after some difficulties I was able to test this. So, for hyper-speed loading you use the Software IEC with the correct kernal, ist that right?

This did work on the C64 while it did not work on the C128. Nice feature - I was able to run games like Oil Imperium and Pirates (not sure if that one is stable), and I guess you could also try to put one of these games on a D71 or D81 to skip swapping disks.

However, the speed was not even close to the speed you could get with DMA load. I tried with a game called Alien Infiltration, after starting the 1st part it took to load 38 seconds instead of 61 seconds which is a great benefit, but still not very fast.

So i'd leave this open, although that new IEC feature is very nice.

From the speed it sounds like the hyperspeed isn't used at all...

[Flexmaen]

Yes. I tried with #8 like you suggested in the other conversation, but it is not really fast.
