My grandfather actually can  , but my granny needs some more time

With ASM glitches, you can put up basically anything that uses the OS for out-of-purpose stuff. By the way, if the words "Application" or "ASM program" or "third-party" occur in your tech-support email, you get the fixed response: "We don't support third-party applications. Contact the developers."

But I guess you meant malfunctioning OS routines
Brandon Wilson 's documenting Bcalls as of now, so he'll no doubt encounter some weird stuff.

About the 4-tile radius idea:

If you use a kind of array to store all the enemies, it won't be that hard to check if one of them is within 4 tiles of you, having them pursue you is harder, but certainly doable.

Hi guys, I've been registered for some time on this site, but 1 post isn't really much... I've been in the calculator community for a few years now, mainly on UTI.

I will be 15 on november 17th, 2009. I live in Belgium, and I study Latin and math in what you'd call high school in the US.

I'm quasi-fluent in z80 ASM, but that doesn't mean I'm 1337, since I haven't accomplished anything notable yet. I know Java, some C and a little bit of C++. It's been more than a year that I've touched TI-BASIC, though.

I'm a bit into randomness as of now: occasional reverse-engineering, small programs, unfinished projects (the 99% share), etc. You get it.

EDIT: I noticed this forum is about music as well: I'm a renaissance music freak (about 1400-1650 is my style), and I play the recorder & the oboe.

EDIT2: And please don't offer me peanuts, I'm allergic..
