Moon Patrol for the beeb (New port, just starting)

Post by tricky » Fri Jan 04, 2019 9:14 pm

I've been thinking about doing moon patrol, I wasn't a big fan and the beeb version really put me off, but I'm coming around to the idea.
The ground is a bit boring at the mo' and this isn't a beebem version :(
I also need to improve my music converter.

Thanks.
I had to tweak my VGM converter as the VGM for the music that I had found seemed to have been converted from ~60Hz to ~50Hz and back to ~60Hz and my converter was finding a 61.75Hz pattern! Anyway, reduced from 1K to 400 bytes and now plays at a speed much closer to the original (now a bit too fast). The "drums" repeat the same pattern, so I could reduce that to 200 bytes!
I have a few minor compromises in mind, but the result should feel very close.
I'm trying to think of a good encoding for the map between exactly the same ground/aliens vs random whilst still making it possible and predictable.
Memory is looking OK, but there won't be much to spare and I doubt that I will have room for the buildings or any extras, but I am open to suggestions.

Tried both demos. Impressed! Eagerly looking forward to the next (and the next and the next and the next! :) ).

Stalled a bit, just can't seem to stay awake!
I'll try to get a new demo by the end of the weekend.

Managed to get a couple of hours to add a longer tune and the buggy - can't be controlled but does have suspension :D

4.5K free :cry:

PS If you have an old beebem, the sound will be awful due to a beebem bug - I will try to remember to work-a-round it for the next demo!

BeebEm version attached - sound is correct in some versions but way off in others!

Looking good Tricky =D>

One of my favorite arcade games that I'd play at the local milk bar.

I'd collect soft drink bottles to collect the deposit, buy some lollies and then have a few plays on moon patrol, good times.

I've been having trouble sleeping and waking up!
Added moving SHIFT/RETURN and shooting up Z.
Debug output says 7K left.
