Deathchase Turbo +

Hey guys

Here's a video of another mod I did of Deathchase, which changes the day / night switch with a continuous game that increases in difficulty and has a day / night cycle as you play.

Re: Lunar Rescue

Another update. The game is now in a 'beta' testing stage. There are a couple of things I still want to do but it's fully playable. The AY sounds have been updated, lowering the volume a little on the landing beeper and matching it to the arcade. The game has been sent to my followers on Patreon. If...

yes, it's like that in the arcade but I was thinking of dropping the volume of it and will do so now you've said that.

Re: Clone Wars (Asteroids): vote

I'd say it's not about finding the perfect way, but rather the best way - I think (1) using the proportional vote to break the deadlock between the most votes, or (2) re-open the voting with a 'golden vote' (i.e close when there is a winner), are both better than going back and changing the whole sy...

Re: Are amiga games bad?

I had an Amiga for about five years and I really enjoyed it at the time. However, if you put nostalgia aside, I'd take the SNES or Megadrive library any day of the week.

Re: Clone Wars (Asteroids): vote

well, you know, it's just for fun, but what i don't understand is that if the proportional vote trumps the entire original vote, why not just use the proportional vote in the first place? it doesn't really make sense because essentially in the event of a tie, you scrap the original votes completely....

Re: Clone Wars (Asteroids): vote

I think in general when you have a tie like this, you use the proportional votes as a tiebreaker don't you? i.e to 'break' the deadlock between the top two rather than reset the whole system? I realise that means Asteroids RX wins, but I would still stand by that method either way.

Re: Clone Wars (Asteroids): vote

Thanks for the votes chaps. I probably shouldn't be allowed to vote for my own game, but just to be clear, Asteroids RX recreates both Asteroids and Asteroids Deluxe. Blasteroids is not technically a clone of Asteroids at all, it's a conversion of, well, Blasteroids.

Lunar Rescue

Here's an update on Lunar Rescue which is being coded in '100% machine code!' live on Twitch. The aim is to get as close to the arcade as possible, as fast and smooth as an arcade game should be with no flicker or tearing. There are still plenty of challenges ahead but it's getting there. https://ww...

Re: A question about conditional jumps in ASM

as with all things assembly, there are many different ways to achieve the same thing which may be better depending on the context, but here is another alternative, if you don't mind using the registers: ld a,(address) ld bc,$050A ld de,$0b0c ld hl,$0f14 cp b jr z,dest cp c jr z,dest cp d jr z,dest ....

Re: A question about conditional jumps in ASM

you could try this:
ld a,(address)
ld b,5
ld hl,testlist
testloop:
cp (hl)
jr z,destination
inc hl
djnz testloop

...no match code here


and then:

testlist: 5,10,11,12,15

Over the last couple of weeks I've been hosting regular live coding streams on Twitch so that every bit of the project is recorded for educational purposes. This week the main challenge was to co...

Re: Whatever happened to...?

regarding Lunar Rescue, I kind of painted myself into a corner with it as it was all coded in AGD. The scripts became far too convoluted trying to do things that it really wasn't designed for. Since then I've learned a lot more about assembly and I will hopefully do it again from scratch in pure ass...

Re: Which ZX Spectrum game is most deserving of a sequel?

Deathchase 2. Generally updated for 48k. More objects / varied scenery. More interactive gameplay, with enemies that actually hinder you / build up / shoot back. Good call, especially if the helicopter could be shot, like the rumour going around my school playground at the time…. The helicopter can...

I'm being pedantic of course but recorded history is about 6,000 years, not really 4 billion. Human history probably about 200,000 years. I don't think people consider games like BC Bill to be historical :P Moving away from the Spectrum, games like Civilisation and the Total War series have covered ...
