Nope, gone on for years now, never gonna stop.

I know what the safest thing to do is. Use a better emulator :)

POKE 40605, 175 seems to let you keep launching a new bomb again but I haven't tested it a great deal. No idea if it works with the superbomb too.

Edit: Never mind, seems like it doesn't always work!

Re: New release of SpecEmu

Well, not for me. All four Midway roms are in the appropriate /pacman/roms folder, but this option still doesnt appear in the Tools menu. I'm using windows 7, but I doubt that's the problem here. It worked fine up to v3.2 build 25/03/23. Try this one: https://1drv.ms/u/s!AmOOhLw8lDDyh4U-4AAs2_mKFGt...

About the latest machine issue: I've also used polomint's SpecEmu version in the past - could it possibly be related to both using the same config file?

New release of SpecEmu

It's been quite a while since I released anything, and I haven't exactly been busy with it, but here's the latest version:

Something quite similar looking although not even close to being in the same league in game play!

Re: Cant find the program with digitized music?

I tried it on the latest SpecEmu in both 128/48k mode, so I have no doubt about the quality of the emulation. Probably I overlooked something, does anyone know how to play this tune? You could use the "Boost saving tone" option in the Tape options to boost the MIC output to an audible lev...

Re: Cant find the program with digitized music?

Last time I tried, it worked fine on my +2A from the covertape itself. No idea why it might fail under emulation. So the +2A (and presumably the 128K too then) produce audible MIC output through the TV speaker with the Beeper bit off? The reason for the silence in SpecEmu is that it's stated in the...

It should indeed say when the low bit is set.

Re: Starting emulator - help with basics of Z80 timing needed

I did not expect an internal operation on the z80 to be contended? They're contended because the ULA doesn't look at the control bus for MREQ signals and the like and only respond to what it sees on the address bus which is the last address latched, or the address of the JR offset byte in this case...

Re: Starting emulator - help with basics of Z80 timing needed

Or another way you can think of it in the opcode breakdowns is to always try to think what is on the address bus at any moment in time as the ULA will contend based on the address bus contents rather than any specific register pair. So your pc+1 address fetching the offset (25 in your example) is th...

Re: Starting emulator - help with basics of Z80 timing needed

Looks like you understand the concept of how to implement the contention just fine but the pc:n (or reg:n entries in some opcodes) are relative to the starting values of the registers at the start of opcode execution. Hence your pc+1:1x5 will be using pc+1 as meaning 25001 rather than as being 25002...
