You store it in the 128? or so bytes of text mem at $80DF. At the
top of the prog you can assign names to locations.
TempByte = $80DF
TempByte2 = $80E0
TempWord = $80E1
TempWord2 = $80E3
You can also do relative location assigning like
TempByte = $80DF
TempByte2 = TempByte + 1
TempWord = TempByte2 + 1
TempWord2 = TempWord + 2
Then to store a you could do a:
ld (TempByte),a
or if you wanted to save hl
ld (TempWord),hl
or if you wanted to recall a from TempByte
ld a,(TempByte)
or TempWord
ld hl,(TempWord)

There is a bitmap to *.85i (ti85 pict format) convertor ouot there.
Then you can use Zshell compressed picture format by Stephane Jantzen
to put it into zshell... You could also uwse a pcx image and convert
it into GCP an improvement on ZCP that allows grayscales. For
sprites, you probably will need to do them manually. Check out NASR
by Jingyang Xu. You can find all this stuff at ticalc.org

Just use the base menu on the 85. It works good enough.
