One Sprite Wander (C64) released

So this release was meant to happen a week ago, but I really haven’t been well… still, here’s One Sprite Wander now, a single sprite 4K intro for the ICC 2019. This was inspired by One-Sprite-Wonder by ROLE from last year, but squished down into the smaller memory footprint and doing a bit more to abuse the sprite.

Along with opening the side borders and splitting a colour register, there’s basically a metric boatload of sprite expansion register twiddling going on to both stretch the single sprite being used vertically and make it wibble horizontally whilst it wanders across the screen.

Eagles Dare (C64) released

It’s “busy season” again, so there’s yet another entry into the CSDb Intro Creation Competition to mutter about! This time it’s called Eagles Dare, has got code and graphics by yours truly – the picture is mostly wired, but I did some work to make that happen and added details – and aNdy handed in another great tune. The memory footprint is $0400 to just before $43ff so this is a 16K intro.

The unusual feature of this one has to be the scrolling message, it uses Extended Background Colour Mode which limits font use to the first 64 characters (the upper two bits of the character code are used to select one of four background colours) but, rather than a fixed character set, the scroller has a 39 character buffer which is scrolled along the line, recycling whichever character falls off the end for the next. This means that any character from the C64’s upper or lower case ROM font can be selected, although the embedded commands for that and those used to select background and foreground colours take quite a bit of space and there’s not much room for actual text in this one!

Funky Stars (C64) released

Just a quick post to talk about Funky Stars, a new release for t’other label from new member aNdy; the name comes from the stars behind the logo and a lovely cover of Quazar/Sanxion’s Impulse Tracker tune. This is also an entry into the CSDb Intro Creation Competition for the 16K category, which is always a Good Thing in my book.

It was something of a surprise to hear that somebody else actually wanted to be a member of C64CD and I had to tweak the CSDb entry accordingly whilst pushing this out… so I wonder if there’s anyone else out there?
