Coding new videopac-emulator

[Dr beep]

After coding a new ZX81-emulator for the ZX Spectrum I will try to rewrite my Videopac-emulator as well.

First view tells me that an updated version should be better than the version from 2000.

Do you have a link to the new ZX81 emulator?

It's in the Brand New Software subform:

I see that the old translateroutine between 8048 and Z80 is not working as wanted, keeping memory emulated, not translated.
Here I can win speed.

I had this project on hold, but no I reactivated it.

First thing I did: I altered the the table with the translated addresses so I now have more room for translated code.

I also decided to do a manual translation of the ROM but that is for later. It is only 1K.
A translated ROM however will give a lot of speed to the emulator.

Now that's really scary I did not realise that the first version was from 2000!

It is and I only have the source on paper and it is far from complete commented.
However... I think I can speed it up quite well.

I used the old source to find which opcodes were never emulated and I will keep it that way.
