Subject: [stella] Weird Loop... From: Manuel Polik <manuel.polik@xxxxxxxxxxx> Date: Wed, 06 Dec 2000 10:33:26 +0100 |
Hi there! In Starmaster I found this loop: LDX #$18 Loop: STA WSYNC LDA VSYNC NOP NOP NOP NOP DEX BPL Loop It's used for drawing 25 blank lines showing nothing, when displaying the Map screen. (The space between the actual Map and the status lines) Now, I've no clue, what the LDA VSYNC & the NOPs are for... Can someone explain that to me? Wouldn't - LDX #$18 Loop: STA WSYNC DEX BPL Loop - do exactly the same?!? (On a first guess I'd say it's just to confuse poor reverse-engineers like me...)
