The 'to do' list is very small now....

Assigned some 'more realistic' high scores, and adjusted the bonus awarded at the end of each level, so you have some chance of the first digit in the score being used ! πŸ˜…

Leading zeroes have been ditched from the high score display....

Won't be long now....

'Search for the Lost Orb' is a text-based adventure game for the BBC Micro that I found whilst going through my disk collection. So far I have been unable to find out who actually wrote it. I asked the people on stardot, but had no luck. I think it could be Andy Bray (RIP) who I knew well BITD.

Just for fun this evening, played Mega-CD Soul Star. Kina funny playing one of my own games, but I was in the mood...

Did make me think of doing a PC retro style version. Same graphics and sound, but running at a much higher frame rate, plus loads more fx sprites!πŸ˜ƒ Hmm... Might do it just for fun.πŸ™‚

Mini break over, back home now....

Just testing some stuff with a non-zero value in the clear screen procedure.... Highlighted a few issues, one with the DUCK sprite where I was wiping a bit too much than was necessary !

Pretty-much fixed, saved some more cycles !

So rolled back a week and did a preliminary run thru to level 12 - no bugs seen !

Now just need to compare all asm files and reintroduce changes I made in the last week until I (hopefully) notice something that will break stuff !

....this may take a while ! πŸ™ƒ

One of the things I wanted to do with my Commodore 64 Ultimate was use the Swiftlink MODEM emulation layer to write some games/BBS that used it. I put together a video about programming it in BASIC.

Its a long at an hour :(

Hope it helps someone though! #Commodore64

Curry with friends tonight when I realised....

Harry is 16 pixels high, that's 2 character rows, let's call them harry_head and harry_belly.

I'm checking both for egg or grain collection. But grain ALWAYS sits on the floor, so I don't have to check his head for grain ! πŸ™„

Saves a bit of code ! πŸ˜…
