SyntaxBomb - Indie Coders

do you remember the user defined graphics chars you can put in a speccy, they had a tool that allowed you to edit them , like a drawing app, anyone have it?

  You're going to have to narrow it down a bit with the number of UDG designers that were written for the Sinclair ZX Spectrum.
You'll find it much faster to get a bit of graph paper, draw an 8x8 grid with columns 0-7 representing a byte and doing it old school.

Try this one https://www.ebay.co.uk/itm/235241061347. Good basic as well! If i remember there's even print anywhere x,y on the screen command.

thanks, but i dont think i can load a real tape. and I had the utill in the 80s and its far better than old scool, but have the correct problem. I may have to code it myself, i was sure you guys would of had a z80 image, I may try archive.org though thanks

@mainsworthy Try looking around the World of Spectrum site.

As @dawlane says try world of spectrum or the the French one EMULparadise.

Baggey

just found this, but dont know if i can save it yet.  but i will look on thoses sites

UDG Maker (1987)(HL Software) : Free Download, Borrow, and Streaming : Internet Archive

ok, im still trying to remember, so is there a command in zx basic to delete the whole program but not the UDGs. if so im good, but new seems to wipe everything

The UDG area is above RAMTOP, and is therefore immune from the NEW command. You can change RAMTOP using the CLEAR command with a memory address. The default RAMTOP is 168 (21x8) bytes below the highest memory address. This means the the bytes that go to make the UDGs will reside in memory and can be used again.

The workflow back in the old days before the use of editors, was to write the basic program to poke the UDGs into memory, while saving it in case of mishaps; and then save that memory block with the command SAVE "10 char string" CODE address, no. of bytes. You would just then load the code block back with CLEAR address-1 : LOAD CODE "" address

NOTE: The 128K ZX spectrum only gives you 19 UDGs because of the two new keywords SPECTRUM and PLAY, that has been added to 128K BASIC. You still can only use 19 UDGs in 48K mode, so you should consider using true sprites, or redefining the character set. GOOGLE redefine the ZX Spectrum character set and search for the original Sinclair ZX Spectrum manual for more information.

 

Another place to look for software is Spectrum Computing.

dawlane, thats great info, and baggey too. Im going to dev for a speccy

You should keep your eye out for The Spectrum Hardware Manual (Melbourne House) and The ZX Spectrum ULA: How to design a micro computer.

Just found this sight it's good https://zxart.ee/eng/software/games/

There are even cassette inlays there

Theres an SCL format not heard of that one need to find out

whey thanks. just trying to setup my deskspace, bad back so its hard to get set.
