RL5203 update 02-03-2022

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

2022 comes to a close, HB notes and updates

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.

Koffi Redux project, recoding dlists and fixing a bug

[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

Koffi designs and grids circa 2002

RE: this thread - https://forums.atariage.com/blogs/entry/16804-cleaning-out-the-homebrew-folders/     I dug out my 20+ year old gridlines notebook to draw some stuff and realized I had never pitched these designs for 2002's Koffi: Yellow Kopter. Posting them in a blog.
