As far as I can see Joefish would like: 1/ To retain copyright; 2/ To allow SC to distribute the title for free; and 3/ Not grant other sites distribution rights. Which is the right categorisation for this? It certainly should not be freeware. That is the definition of freeware, the fact the author...

I saw the thread title and thought "Well that'll be Cyclone as #1 then". Shocked to see it missed off, one of the best games on the 8 bits full stop.

Better than Zynaps?

Well now I have none. Dammit.

So difficult to pick. R-Type feels like it deserves a place, but that excludes Robocop and Rainbow Islands. I think the only choice I'm not conflicted with is ZZoom and only because I wasn't a fan of Zombie Zombie.

This is the scenario: Stack below 24064, main code fills 24064 up to the top, including vector table at 65024 in main (=bank 0?) filled with db 253, JPs to interrupt routine at 32768. Interrupt routine will page in bank 1, call AY music there, then page bank 0 back in. If you're using an original 1...

No. As long as the I register is outside the $40–$7f range, you’re good. Also, the kosher way to return from an ISR is RETI, not RET. ;) Not strictly true. If you set the I register to a value between $C0 and $FF and have contended memory paged in at $C000 you will crash an old school 128K (but not...

Has to be Jet Set Willy, it was probably the first exposure to truly "open world" games and provided endless fascination just wandering off to find new rooms - trying to actually complete it wasn't even part of why I played it back in the day (though I have done since). Not until the likes...

Memory Indirect would suggest a level of double indirection, in the same way that Register Indirect does. So if ADDR was 4000h and the value stored at 4000h was 8000h, the a memory indirect load would fetch the byte from 8000h. That's not something the Z80 supports. LD A, (ADDR) is just plain old in...

The Gate Array in the CPC holds the interrupt line until the Z80 acknowledges it, which is why you won't miss an interrupt there (well unless you DI for long enough that multiple interrupts fire). IIRC the Speccy, in contrast, just pulses the interrupt line at the start of the frame. That has the ad...

Honestly, there's a pretty good reason Nintendo weren't happy about it. It's a fairly terrible game on all platforms.

I suspect now is not the time to have that conversation, everything is still a bit raw, but I'd much rather a forum that allowed discussions about the wider scene (warts and all) than one which arbitrarily shuts down conversation without justification.

Robocop 2 and Where Time Stood Still are the two that immediately spring to mind.

If you need the AY routine to be called at 50fps but don't want to wait for HALTs, why not just call it from within the interrupt handler itself? Your music might go iffy I suppose if you DI for too long, but that's probably as true for any other strategy. Alternatively count frames in the interrupt...

There was definitely some talk of how you could do it, back when the game originally came out for the C64 and CPC. Don't remember anyway actually starting it though. Looking forward to seeing how it comes out.
