[EDITED again - added a Before and After pic below]
Back in 2020, I started to tinker with my old 2002 game, the 32K Atari 5200 homebrew Koffi: Yellow Kopter. I'm calling it Koffi Redux so far. I fixed bugs, tweaked gameplay rules, rewrote various graphics routines to make more efficient, added some colors and graphics, and added 2-player mode. One nasty bug was in the original on stage Windy Vines - it took AA member @RB5200 to find it and report some clues to me. The bug
I figured out why using the TASM .TEXT command was producing junk at times. It was because the 'pretty font' I used with Adventure II XE, font1.s, had the characters switched around and some were actually replaced with custom chars. Standard ASCII and ATASCII has lower case letters from $61 to $7A, and upper case letters from $41 to $5A. But this font1.s had upper case in the range $21-$3A. I had a temporary programming fix which got the upper case letters to work, but I kept noticing oth

But I wanted to start using the most recent DASM 6502 compiler. Many of the code formatting changes were straight forward to see the problem and easily change, but I spent some time trying to figure out why I kept getting unresolved symbols on "A" and "a". I'm not sure if DASM can be configured to show me the li
2022 was a busy year for me. I didn't have free time or mental energy to do much homebrewing on Atari XE or 5200, which I had wanted to. On the personal real-life front, 2022 took everything I had. Full-time job. Family obligations, of course. After a year of searching and looking at houses, I successfully found and bought what we wanted (many other properties I was outbid on, or the property sold before I had a chance to make an offer. The real estate market was crazy in 2021-2022
