Woohoo, I survived another year! F15 D’Gamma Clone is a C64 conversion of the 2016 C64CD release of the same name on the Apple II, with some fairly serious modifications to keep the memory footprint down and add a brutal conversion of Ben Daglish’s music from the 16-bit game 3D Galax by aNdy.
The most significant change is that the C64 version is using characters – under 3.5K in total for the screen and font data – compared to 8K of bitmap data for the Apple II original; it would have been possible to get that code running directly on the C64 but there was no way it would fit into the ICC‘s 16K memory footprint with the extra colour data and music.
You wait for an ICC entry to come and two arrive at once… Femtotro 2 continues where the original Femtotro and its smaller brother Zeptotro left off by running the entire intro apart from the music in the screen RAM. Strictly speaking, it’s a 1K intro with just shy of 2K in music attached to it and there’s a little conditional assembly in the source which allows the code to be assembled without music, replacing it with the classic intro “hum” sound. Both versions are included in this ‘ere video.
The other intro Yoctotro is a little more… extreme on the size coding front, cramming the basics of an intro – a logo, scrolling message and that intro hum again albeit at a different pitch – crammed into less than 300 bytes, starting from the first line of the logo at $07c0 on the screen RAM. This isn’t entered into the competition and could probably be pared down even further if the colours and sound were removed, but I liked the overall look as is and anyone who fancies taking it to extremes can mess around with the source code at their leisure.
So yes, that’s two more releases for 2019 and I have one more intro which should escape before the competition deadline, so yays for that! And on the subject of releases, it’s not entirely mine, but Gerliczer has taken the source code for the C64CD release Stercore 64, ported it to the Plus/4 and released it as Stercore 264 a couple of days back…
…so, whilst I don’t entirely understand the almost unanimously positive reaction it’s received, 264 series owners can now shoot small spacecraft whilst brightly coloured, attribute-based backgrounds scroll by!
Things are certainly getting busy in the CSDb Intro Creation Competition… and there’s another C64CD entry from aNdy to enjoy as well now! It’s called ICC Anon and, if the screenshot in the thumbnail doesn’t give the game away, is themed around a certain unidentified hactivist group and in particular the Guy Fawkes mask that has come to represent them.
There’s also a bit of lower border use; the basics of taking those borders out are relatively simple but, because those parts of the screen were never meant to be visible, it takes a bit of experimentation to work out what the hardware sprites are going to do there. Since this is aNdy’s first go at using that area it came out well!
