Awesome! Thanks. SO glad it looks good on a real monitor. My SCART to HDMI ruins the interlace mode so I can't tell how it really looks. I need to set some time aside to finish it off.

Now if you had a HDMI CRT monitor, that might be different. Ready to leave the Los Angeles area, Robert Bernardo Fresno Commodore User Group www.dickestel.com/fcug.htm |

I still need to try this game! (Been busy with SAM 128)
But I wanted to note that any modern consumer television (even LCD/LED) which has a composite (or unlikely, S-Video) input has to at least emulate scan lines because virtually all composite signals use interlace video. The main exception being "primitive" hardware like the C64 and Atari-2600 which generate non-standard, non-interlaced video.
As far as computer monitors go, I'm not so sure. But I do know my old ATI video card could generate interlace images on an (S)VGA monitor...

(snip) As far as computer monitors go, I'm not so sure. But I do know my old ATI video card could generate interlace images on an (S)VGA monitor... Emulation is correct. As written at en.wikipedia.org/wiki/Interlaced_video"Only CRT displays and ALiS plasma displays are capable of displaying interlaced signals, due to the electronic scanning and lack of apparent fixed-resolution." and "ALiS plasma panels and the old CRTs can display interlaced video directly, but modern computer video displays and TV sets are mostly based on LCD technology, which mostly use progressive scanning. To display interlaced video on a progressive scan display requires a process called deinterlacing." Here is an example. In testing for the John Carlsen C128 VGA adapter ( bit-c128.com ) prototype, we used an older LCD monitor he provided. When the 80-column Masterpaint was run, it correctly displayed on the LCD monitor. However, when we used the interlaced, 80-column iPaint, the LCD monitor could not display anything (i.e., the screen remained black). The LCD monitor didn't know what to do with the 80-column interlacing, i.e., it couldn't deinterlace the signal it received. Perhaps newer LCD monitors are better, Robert Bernardo Fresno Commodore User Group www.dickestel.com/fcug.htm |

I think it's more to do with the timings of the modes. Interlace is simply the process of sending a different image half the time. The TV just sees 50 frames and puts half on even and half on odd lines making 25 "pictures" per second.
The Adapter I have seems to work with the Amiga I am now trying to set up so I am very sure it's just timing issues with the C128, old CRT monitors were much more forgiving than modern equipment that expects things to be very close to the spec.
It would be interesting to connect some old school video monitoring equipment to the C128 and analyse the timings it outputs. I know I had a nightmare getting interlace mode working. Maybe I should hook up my scope.

Ok, I got onto this again and have implemented some compression for the levels. I have also started to finish off some of the missing parts of the game engine so I can make more of it playable.
I'm planning on doing the BD font when I get the chance to put the timer, score etc info on the screen. So progress isn't dead, just slow. I have paused plans for sound at the moment while I fix up the memory issues.
If I can get it under 32k I would like to make a C128 cart for it, so that's my goal. I don't know if I can manage that though.
