HI Buka!

You did a nice job, congratulations!

I suggest you put the UDG chars in RAM between $2000-$4000 so it can be used in real hardware (with UDG board) and in emulator too. For use with EO emulator, set the 'Chr$ Gen.' to 'Sinclair' or 'CHR$16':

I prefer to set to 'CHR$16' because it works with HiRes WRX simultaneously. ;)

In EO emulator next page, "advanced settings" allow 8-16k RAM easy, UDG too. ;)

I can easily change the program, a set of characters easily send the right place, and change.
By default, did h2000. In the emulator works (although there and 1E work ...). ;)

Mistake 4 again here - you can easily remove the two DIM on 960b, but the game will be really quite slow. Fixed in BASIC, and the file will be there.
Summer in the northern hemisphere it is, laziness Assembler remember! ;)

All right, now this program can not be called a "pure BASIC." One line of code there. ;)

UDG now H2000, everything works. In the emulator ...

Will report the XuR test...

Another way... on a true ZX81: "CARAC"[HEBDOGICIEL]
or Cramp[HEBDOGICIEL]:

Wow! How I missed this! :shock:

While yes, the search program like Google, bad looking in different languages.
A lot of French sites I missed ...

The French Vb81 XuR will help you to create UDGs (ROM ; binarys]

Yes, but when you write a program Vb81XuR three times destroyed the result of long work. So I wrote to the EO, only occasionally checking compatibility with Vb81XuR. And edited the UDG, yes.

And I still do not understand why when booting from *.p file after the FAST (and tuned to blanking the screen), this emulator is still sometimes (SOMETIMES) show the picture. Using the T81 is no such problem. Riddle ... ;)

Hi Buka,

Gooooood Job !
147 bytes free on your 16k ram pak.
It will be difficulte to get rooms in this program...
Perhaps rebuild the Basic lines using "AND" functions (not if...) and reduce basic lines.(POKE xx,xx +( x and xx)+(y and yy))
I try to add a text compressor "CAT " >> "C" +"AT " function in text.
