Ich bräuchte mal wieder Hilfe mit ASM, und zwar habe ich die Urchin disassembly (wall following) von der SMWC Sprite Section runtergeladen und will ihn als Custom Sprite einfügen. Ich will aber einen etwas schnelleren Urchin als der originale Sprite, kann aber in der Datei nichts von "speed" finden, und der Code sagt mir nichts.
Hier ist der Code, und danke für eure Hilfe!

"Routines from the library which one shouldn't have to modify" hab ich mal rausgelassen.
Exits done: 42, Overworld: 80%
To do list: Castle #5... fast fertig... Danach gibts endlich die Demo
