LittleFM on GBC

February 7th, 2010

I finally felt motivated to work a little on LittleFM, and the next feature in the pipeline was (the comparitively small) feature of “real” GBC support, ie support for double speed and colour palettes in LSDj which LittleFM has been lacking so far. (Instead it used the oldschool compatibility mode which didn’t allow LSDj to take advantage of the higher CPU speed found in the GBC)

It works great and flashing takes about half the time when done in double speed mode, however I forgot to clear the secondary GBC bakground map when going from LSDj back into LFM, using the classic sel-start-B-A combo. What this means is that the colour pattern from LSDj will not be erased but remain on the screen. This gave this nice visual bug seen below. As you can see, the pattern resembles LSDj’s screen layout.

I’m going to finish one more feature before I release LittleFM 0.4, loading and saving of individual LSDj files, so LFM can truly replace the builtin file manager that comes with LSDj. I have an almost working version of this feature, but it has wrinkles which I want to iron out before releasing it.

The last picture is shitwave which actually looks marvellous with the backgrounds residue. It gives the vibrations more life and you can see what’s actually happenening rather than just vaguely vibrating lines. It may not be apparent on the still image, but it looks nice live.

Sorry for the long wait, but have patience!
