Impressive... now explain how does it work.. xD
I guess you are redirecting the char lines in the rom but stil maintaining the slow tex mode...
I can't imagine how did you do this

Wow ... that is definitely some witchcraft! Very impressive!

Fascinating...combining four display lines at once.
dr beep is a WIZARD! (and I really do mean that in the nicest way possible)

[dr beep]

The display is executed 8x to form a character.

After 1 line the ROM test C for reaching 0. C is hardware connected to characterpointer.
When C <> 0 a POP DE is done to keep HL on same line, when C=0 POP HL is done to go to next line.

Make a screen like this
Dfile 118,118
Char db “H”-27
Ld h,d
Ld l,e
Db 118

Repeat char—part to 118 4x

Then place 1 db #e9
or 22 db 118 to make a full screen

You now have a single H character on screen.

After executing a line DE points to next line. The ROM executes HL again, but at the end now HL is loaded with next line.
After 2 lines the ROM goes to next line but C pointer is still working.
You can now alter a character while displaying next 2 lines of a character.

Alter last 2 “H” in “A” and see how your display alters the H in a more dense H

I will post the source later.

You need 2 118 at the start to have DE right.
With some trick it is possible on 1 line but that is harder

I make dfile point to the next line to display after displaying 2 lines.

First effort was just to swap EX DE,HL but that
only works with 1 full line (8 lines).
The LD H,D LD L,E can have
a full screen of altered characters.

I still have an idea for another trick but that will be later this week when it works.

If ANYONE can make a video on real hardware.
Please... I would like to see that.
