Yes, a great version. Frogger was also based on a Konami Z80 + AY.
An arcade emulation was fine too, so I don't know if he had "steel" the original routines or redone all.

"The game uses two Z80 microprocessors and two AY-3-8910 PSGs for sound." Not sure how feasible it would be to emulate it?


To be exact:



Main CPU : Zilog Z80 (@ 3.072 Mhz)
Sound CPU : Zilog Z80 (@ 1.789772 Mhz)
Sound Chips : (2x) General Instrument AY8910 (@ 1.789772 Mhz), (6x) RC (@ 1.789772 Mhz)

The game looks simple enough, except for the scrolling. Can the CPC do it that well?

The bg is solid, only the clouds (things floating around) move. You don't need masked sprites for that (although you'll need them for everything else).

Not sure if the playing area could be that large, but I think it would be doable.
Released The Return of Traxtor, Golden Tail, Magica, The Dawn of Kernel, Kitsune`s Curse, Brick Rick and Hyperdrive for the CPC.

If you like my games and want to show some appreciation, you can always buy me a coffee.

Sure, I know that. But I think it is not a real problem.
In arcade, multi-CPU are mainly used because each of them access its dedicated ROM, not because power is required...
Loading from a floppy and using the CPC expansion RAM bank switching should resolve that with only one CPU.

About the 2x AY and the rasters display, the PlayCity can perfectly do the arcade job.
Else, yes some channels will be cut to ear others...

Finally, there is no scrolling if you remove the clouds as the ship is always at the center. ;D
That means, only sprites are moving around it and masking should be not required.

Ok, sound will probably use up around 10% of the CPU time, maybe 15%. So one Z80 should be enough. And for the two AY's we got TotO's nice PlayCity.  :)


(I'm more concerned about the way the background scrolls, there seem to be two levels, but I may be wrong).
