The next version of Total Replay will show super hi-res artwork while loading a game on supported hardware. This works on the 16-bit Apple IIgs and any 8-bit Apple II with a VidHD card — even an Apple ][+!
More than ⅔ of the games have artwork [thanks Alex L, Andrew R, et al.]

Probable (short for "ProDOS-bootable") is my new 496-byte Apple II utility to run DOS 3.3 programs on ProDOS: github.com/a2-4am/proba...
Probable runs on any Apple ][ with 64K and is compatible with all ProDOS drivers. Most DOS programs can quit gracefully back to ProDOS by pressing Ctrl-Reset.

Reverse engineering the 5-bit text format used in Transylvania (1985, Polarware, Apple II) in preparation for changing the prompt from 3 save slots to 9 because I love you
![game text is stored compressed similar to ZSCII
5 bits per value, $00..$1D are index into table 1 (lowercase letters)
$1E & $1F shift to table 2 & 3 then use next 5-bit value as index

new prompt

Here's a teaser of my and qkumba's next project: Adventure Replay.
A pack of Apple II graphic adventure games, patched to launch from a hard drive. Search by name or browse by year. Each game lovingly patched with enhanced input routines, additional save slots, and of course no copy protection.

I really, truly can not express how mind-blowing this Windwalker title anthem is. This is a stock Apple ][ running at 1 MHz. No third-party sound card. Just the built-in $C030 speaker that blips.

What's your "no one remembers but me" game?
Tough question because several of my friends specialize in preserving obscure games, but I'd have to go with Micro Golf (1981, Creative Computing). It was a 9-hole mini golf game for the Apple II. I played the hell out of this as a teenager.

Today's aesthetic is this full-screen scroll & palette inversion (Windwalker, 1989, Apple II). This is standard HGR graphics; the entire game works on an Apple II Plus from 1979.
