Wow.. This forum is great. Made me laugh so hard.
I'd post some of the stupid code I've done, but i'm NTSC. Nuff said?
Honestly, I think the stupidest code i've written was this:
lda #$0b
clc
adc #$1f
sta firstline+1
tax
lda $2000,x
sta $0400,x
clc
rts
I think I used it for a cheesy text displayer. Changing either the #$0b or #$1f created a different text display effect (thinking about it, I used this in WICKED/FOE).

Yes, try it in this thread too... :-(
I guess we gave you enough sourcecodes and hints to get you going.
