Nekem a hét eleji játék kijelölés, és mondjuk szombat 23:59 teljesen jó határidőknek.
Azt nem tudom, hogy a demo mekkora fájl lenne, szerintem még sose csináltam :D

i will try to create one file from sources, i hope, it can be managed. Until now i could manage these kind of activities, and i hope it can be done for IS-DOS also.

There could be more reasons of problem, Spemu checking byte patterns after or before OUT or IN instructions, probably those programs have different byte patterns before or after, other ptoblem is ROM writing, what is used by several Speccy programs ( this can be solved by ROM version of SpEmu), other possible problem is finding things about IM2 interrupt, and probably there is more, just i got to my mind the above mentioned :-D
I got another thing, Nirvana and other programs which are using similar attr refresh method do not work either

Thank you very much Zozo, it really seems to be hard, I hope we could create to reproduce the source of the actual binary.

Sorry, i forgot about ROM writing Speccy programs, there are quite lot.

Yes, because there are some (about 5-10% ) CPC programs, which uses only ROM calls :-D There is nearly no Speccy programs which uses only ROM calls ;-)

I checked, only 5 million Speccy were sold,3 million CPC, 12,5-17 million C64, and 8 million PCW, i have never thought that.
Sorry for the off.

I wonder , so much PCW were sold? 8 million sounds very much, it is close to the number of sold Speccies which is above 10 million if i know well, but none of them is close the number of sold Enterprises :ds_icon_cheesygrin: :ds_icon_cheesygrin:

As i see ZXM works the same like old Ep software Speccy emulators, only basic programs run on it, except those machine code programs which use only ROM calls (CPCEmu works in the same way)

it is impossible to write so fast Speccy emulator on CPC like SpEmu, because CPC does not have attribute mode, and does not have LPT, so if it could be done in 2 or 4 colour mode , then Speccy addressing should converted also, which i think nearly impossible to create a good algorythm to find out all writes to video memory, and convert all routines, one way is possible, convert the whole speccy screen, but in this case all 6912 bytes have to be converted on CPC, SpEmu converts only 768 bytes of attributes in 3 frames by default, it can be changed.

So according to what you explain here, the software emulator must have been better than the hardware one! Amazing!!!
It is, probably it's compatibility is lower than the HW emulator with new ROM, but it is faster if bigger amount of attirbutes are changed on the screen, and it does not slow down when the program has high beeper activity ( because OUT (0feh),a instruction is changed to OUT (0a7h),a :D :D :D )

Emulators / Re: Double software emulation on a stock EP128

thank you very much :-) it is nothing special, just i got some good ideas to my mind, there were modified Speccy ROM's on EP from the eighties, which worked well, just machine code programs did not run, because almost all programs used the HW ports, not ROM calls, and tried to "emulate" them too.

The problem can be caused by spemu, because it is not a real emulator, it convert speccy programs after loading, and patches the interrupt of the loaded programs also that's why menu can be called anytime, if a game does not use interrupts, i put menu call code into keyboard emulation also :-D

It could be great to upgrade from 2.2 version to 3+, profiting from the Enterprise memory paging capabilities.
But i think it would be also a bigger task, hard to do by patching the code, the source code would be needed also for this action.
