Dabz	After the youtubey post here:- https://socoder.net/?topic=5222&seenpost=51317#51317 I've converted it [sorta] to assembly (Maxam based) and its turbo'd right up!!! ;;The start of our program in memory org &4000 ;;Setup for our return to BASIC push ix ld ix,0 add ix,sp push af ;;Set Mode 0 ld a, 0 call &BC0E ;;DE is our counter variable for the loop ;;e.g. &C000+DE ld de, &0000 .loop: ;;Loop through screen memory and store a byte (&0c) at address based ;;on where the counter loop is (Linear addressing) ld hl, &C000 add hl,de push de push hl pop af pop de ld (hl), &0c ;;Swap this to the letter l for different colours ;;16bit loop guts, this is how we manage to navigate 16bit (2 byte) addresses ;;using 8bit instructions, remember the end of video memory is &C000+&3FFF, ;;so, we need to split the address down to two bytes and work on each byte ;;seperately... What a palavor!!! :D inc de ld a,e sub &FF ld a,d sbc a, &3F jr C,loop ;;Wait for keypress then exit to BASIC gracefully! call &BB06 ld sp, ix pop ix ;;Set Mode 1 ld a, 1 call &BC0E ret ;;TADAAAA Jazz hands --v Go me!

Hotshot	Does this Assembler seem to be easier than Asm 6502?

Dabz	Havent a clue HS matey, I used the built in assembler of WinAPE, which is Maxam based. And Maxam was very much THE assembler for the Amstrad CPC! All in all though, this was fun!

Dabz	So, yesterday, it seemed everyone was busy... I wasnt an exception either... May I introduce... ArnIDE:- View on YouTube It uses SDCC as the backend to build projects, the highlighting is a bit... Meh, ~~but, that apparently is Scintilla's default C/CPP lexer... Which is bloody shit really!~~ Apparently that was just me forgetting how Scintilla works! Anyway, yeah, got myself a nice little all in one dev system for the old amstrad nearly there, "Build and Run", it's defo the future!

Dabz	I'm loving these little videos mind:- Here's the editor, better highlighting cos I remembered how Scintilla works (D'oh)... and a nice peek at a tilemap:- View on YouTube Giddy up!

Jayenkai	Awesome work!!!

Dabz	Tar! It's still a touch quirky in parts, but overall, you can build and run guff! -=-=- Intel Core i5 6400 2.7GHz, NVIDIA GeForce GTX 1070 (8GB), 8Gig DDR4 RAM, 256GB SSD, 1TB HDD, Windows 10 64bit

rockford	You really have no idea how much I hear that because of my nickname! It may have came from my sub-conscious, because I certainly never even gave that a thought intentionally. Sorry.
