Assembly programming?

  InterruptRequest

   Is it at all possible? There's this book on amazon, dealing with
   programming in assembly language and I'm interested, but only if it's
   possible on the C64 mini ofcourse.

   [2]InterruptRequest It's definitely possible, yes! There are several ways
   to do this.

   You can program in assembly on the device using Jim Butterfield's
   Supermon. It isn't a symbolic assembler, so you need to know where jumps
   and branches are going in advance, but for short things and programs from
   books, it will work great and includes a disassembler. Like (almost)
   everything that Jim (who sadly died in 2007) wrote, Supermon is public
   domain and has been preserved on GitHub:

   If you have a C64 assembler package in disk form, you could try that.
   There were several available that had some great features. Many were on
   cartridge, though it is hoped cartridge image files will be supported on
   the Mini soon.

   Probably the easiest way, and the way I currently program for the Mini, is
   to write elsewhere and convert to a file, load it onto a disk image and
   transfer to the device. I've been writing such an assembler for a while. I
   still need to add some documentation which I'll try and do over the next
   week. I've written so many 65xx assemblers over the years, but never seem
   to be able to find them when I get a new toy (hence having written so
   many!). [4]https://github.com/markbush/6502-assembler

   [5]RetroBiker Cool it's great to know this is still possible. So I can
   just fire up Supermon and code away? Sorry but my coding's kinda rusty at
   the moment.
   Now, did or did I not throw away my "Assembly coding for the C64" book?
   I'd like to get into all these irq tricks like sprites in the border,
   parallax scrolling, multicolours etc. [6]:)

   [7]InterruptRequest Yep. I use Supermon a lot. Works great.

   Coding? Ugh! Horrible hipsterish word. Surely you mean programming?

   what you want is cbm .prg studio from ajordison.co.uk

   its the only way to remain sane coding the c64 these days. and yes,
   coding. i used to say coding decades ago when doing demos on the amiga and
   st when the word hipster wasnt even a thing.

   Looks like a great tool. [9]😀

   Shame it's only for Windows. [10]😞

   [11]walnutwhip A good recommendation, I stumbled across this myself a few
   weeks ago and am loving using it!
