Quite likely to have more RETURNs than GOSUBs

GOSUB <key-routine>

LET i$=INKEY$

IF i$="Q" THEN LET Y = Y + 1: RETURN

IF i$="A" THEN LET Y = Y -1: RETURN

IF i$="O" THEN LET X = X - 1: RETURN

IF i$="P" THEN LET X = X + 1

RETURN

How about Wild West Heroes, it's a simple Robotron clone with autofire and lots of very simple sprites (they're not even animated). It's my go-to mindless violence fix

I've been wrong on this count before, but I don't think Spectrum Gamer has been mentioned here yet https://www.cooolapps.com/zx-spectrum-gamer/?fbclid=IwAR1PvVycTpdP9CyaC8752oWZG1tQjKglq4nNKQPuhfRL7p9HYwH9aXQIgz8 Some of you might have seen it discussed on FB Group ZX Spectrum I think it's still qui...

He does seem to be vaguely associated with Design Design, see this article https://www.crashonline.org.uk/08/rebirth.htm

After Ocean he went on to work with Ultimate / Rare ... quite a CV

Haven't used a ZX81 since 1981, I was curious too, found this

The only drawback with using Frames as a timer is that you're assuming the interrupts are always enabled. The ROMs BEEP will disable interrupts temporarily, we can't be sure what compilers might do with interrupts, especially compilers with different trace levels like MCoder. Quite likely nothing, I...

There was also a character scroll upwards in that video used to clear the screen, but that's quite easy to achieve in basic by printing at the bottom of screen to force a scroll, you just need to do a POKE to suppress the "scroll ?" prompt.

A few more that I had links for but were not in the database, there are all assembly again https://spectrumcomputing.co.uk/entry/2390/ZX-Spectrum/Hungry_Horace https://skoolkit.ca/disassemblies/hungry_horace/ https://spectrumcomputing.co.uk/entry/4549/ZX-Spectrum/Skool_Daze https://skoolkit.ca/disas...

The following have source code here https://github.com/pobtastic/ultimate , the first 2 in the list already have source code listed at another Github location The others had no source listed. Safe to say these are assembly also https://spectrumcomputing.co.uk/entry/9305/ZX-Spectrum/Atic_Atac https:/...

Here are some more games not marked as having source available, but for all of these the source (and in a few cases some updates) can be found at https://www.desdes.com/products/oldfiles/zeus.htm , and they're all in assembly (Zeus, unsurprisingly) On The Run https://spectrumcomputing.co.uk/entry/35...

I know Waldroid was joking, but clearly if you want to compare timing of certain instructions it's probably better to loop through it a fixed, larger number of times, say 10,000 MCoder and MCoder II were integer only, and had a few other restrictions quite well documented in their instructions - arr...

Compiled games can often call a machine code routine for sprites or scrolling. If your reference to "recent posts about compiled games" means the ones I was trawling through with source code, we could probably find a USR keyword in the BASIC.

Well I finally bit the bullet and forked out about 100$ for a Powkiddy X55, it's had good reviews and I was looking for something with HDMI output Connectivity to additional controllers - Bluetooth + USB Emulation of Spectrum, Amiga, Atari VCS (+ others) Really wanted to do everything with my phone ...

What editor are you using now BASINC, ZX-Editor or still a standard Spectrum emulator ? Can you send a screen shot ?

I would recommend using BasinC as your Basic editor / monitor - the editor is designed for use on a modern keyboard and it much much easier than using a standard emulator with the original editor (cut and paste helps a lot), plus you can single step through basic programs with windows showing values...

Despite having many friends that played computer games, quite a few in the business, and having been to plenty of trade shows, I've only ever had one encounter with a CPC. I was in John Menzies in Uxbridge and a CPC had just been put on display, all plugged in with the manual beside it. "Hmm......
