Re: The best Speccy game by Infogrames: vote

Sim City is a fine port, but that’s what it is—a port. North & South is an original game developed and distributed by Infogrames, and it’s a brilliant idea brilliantly executed. My vote goes to it. Hostages was an ambitious undertaking, but I think it is was too much for the Speccy to handle sm...

Fair enough, but then you need to emulate the halftone grid in the colored portions of the J-card, apply some relicing, and convert the whole thing to CMYK. :lol:

Re: Super rare old Spectrum game discovered!

There’s a couple of typos that need to be fixed in the loading instructions: tap —> tape, “symbol” in “symbol SHIFT” needs to be capitalized, and I’m not sure if the “R Type Loading Error” is a nod to Dave or also a typo. ;) P.S. I’d use straight quotes (shocker!) for the LOAD "" instructi...

Re: Some gigascreen game prototype: need input

Okay, this is pretty darned good. Can’t test it on real hardware at the moment (but could set it up in the future: a Toastrack or a +2B with a CRT TV), but it does have minimal flicker in RVM. Frankly, I see the smoothness of the graphics (i.e. the number and quality of extra sprite frames) as a big...

Re: How much self modifying code was there and did it do anything?

I use SMC all the time. Mostly to save on space and speed up code execution, but occasionally I replace opcodes on the fly, too. All very useful stuff for 8-bit micros, where every byte and T state counts.

Re: Learning machine code

Back to my question how did anyone learn when the reference books (and magazine type-ins) were riddled with errors? Yeah, that was a bummer. Here’s the thing, though. It’s a mistake to think you need to learn machine code . In reality, machine code in and of itself is quite simple. What you really ...

I concur. Would could do a poll, but the winner is obvious. I, for one, would be voting for it.

There was also the Currah MicroSource @1024MAK. https://spectrumcomputing.co.uk/entry/1000080/Hardware/Currah_MicroSource I don't realise until today that this device offered Forth too!
