I was pretty loopy and bleary eyed by the time I got around to adding the 12/24hr switch. It was the last thing I added. I've still got to do some fiddling to get the timing more accurate. I might need to get rid of the INTIM counters in the VBLANK and OVERSCAN and do a cycle by cycle count instead (GASP!) As well as very closely count my scanlines. Right now the darn thing is gaining a half second ever minute wich adds up pretty fast. But I should have all the kinks worked out by the end of the week. I was really quite suprised at the demand I got for that first clock demo of mine on a cart. I only made it to see how easy it would be to build a clock for the V-pet and was suprised that more people were interested in the clock than the V-pet. But I decided if I was going to release the clock on a cart I should take some time and jazz it up a bit. Thank Bira for the long weekend. I finally got some time to do some coding. Now if I can just work this video clock into a set background on Drew Carey or Friends I should be able to retire on the sales it will generate. ;) ~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~ >Your clock program displays colours on my PAL VCS and strangely enough >the B/W switch is also detected. :-) ~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~ Woohoo!!! Then I'll have to remember if I touch the scanlines while fine tuning the timing to add or take away from them in twos. I guess whatever is at that zero page location I was reading just happens to be an 8.
