Hummm. The way that "struct" thingy works in that assembler is totally backwards. Putting the symbol name after a DB or DW? That's just wrong. Using a SEG and some "label DS 1" statements would be much more normal. Also, the SETDP pseudo-op seems to have been implemented as DIRECT for no particular reason.

 

At least the macros and conditionals are somewhat compatible with the way I do them in my own assembler. The main difference is using the backslash to replace parameters without whitespace, and \0 for the number of parameters. I went with the C-style ##.

 

This thing written with a few too many assembler-specific features to assemble as-is.

 

EDIT: and ugh, he's using "SP" instead of "S" in one file! the Motorola-style purist in me is not shocked, shocked I tell you!

 

EDIT: and... and... and he's letting the assembler automatically turn BRA in to LBRA for him! the lazy bastard! :-)

Other than that (...) it's fantastic Ville released the source of this *great* conversion of Thrust for the Vectrex! A great help for starting Vectrex programmers !

 

 

Those who didn't play it yet should definately download the binary, also up on Villes page at http://www.emix8.org/files/vectrex/VectrexThrust_101.zip, for use in your emulator or flashcard.

 

And although I'm in the very very beginning stages of understanding assembler (Have you got a tip for a good doc on basic assembler, mr. Tomlin?) , at least I learned there's a hidden bonusgame I didn't discover yet
