Just for fun:

C64 roms v2

Spoiler: ShowHide


For Amstrad CPC 6128, QWERTY, not Schneider! (Needs Amstrad branding name in startup-message)

Attention! Because of the flashing cursor and forced CAPS LOCK on startup, the OS rom isn't designed for serious CPC usage!

BTW, this is easy to hack out if you felt inclined to do so...

I mean you had an hidden machine as an easter egg, wasn't it a C64 ?

I'm sure the same effect can be done in 1KB file without changing ROM. :)
In STARS, TREK is better than WARS.

You should do these from other systems, such as BBC, Spectrum, Atari 8-bit etc.

Nope, it was an Atari XL emulator...

Sure it can, but thats not the goal ;)
Goal is that the CPC looks like a C64 (Or another machine perhaps) on power-up :P

BBC, Atari 8 bit, maybe...
But speccy would not work, as expected, because you'd also have to modify the CRTC registers and screen offsets

To do Speccy you can use command WINDOW 5,36,1,24 and similar with ORIGIN. That's it. ;)

Typography in 8 bits: System fonts » DamienG

I know this is much more work, but maybe better made ROM or program which can simulate Basic from other machine not only look.
To make this easy no POKE CALL etc. rest command may translate to Locomotive Basic and execute. :)

Here you are, those fonts ready to use. And from 16bit computers too. Art Studio .fnt type (768b). Sorry I don't thought about this early.

On this dsk is mess some program are not finish.
But "0.BAS" can run and show few kind files. You can try. Use arrows or joystick and Return or Fire to choose. [C] or Fire2 to other disk. ;)
TXT files can be straight from PC Windows-1252 standard, with German France etc characters. SCR only compressed.
"8&16bit.bas" show all this fonts from other machines at once.
"8bit.bas" - trying pretend other machines. After READY type "cont" to look next start screen.

Do you remember POKE to CapsLock on ?

And about others alphabets including exotic.

All of them, plus oryginal fonts from ROM other 8 and 16 bits machines are on this DSK above. :)
Do you like it or hate it? ;)

Does the Amiga one go through the boot up process colours and show the "Hand with disk" screen first? That would be cool, but probably not fit in the ROM.

Bryce.

Devilmarkus

Sorry, but that is impossible. Also the Frame around the startup message is not possible...

I love russian ROM. Great colors and (c) sign superb. It's look more russian than any russian computer I ever seen. :D
I think Atari should have little bit darker colors like INK 0,1:INK 1,20:BORDER 1

Of course this change is enough to make first impression. But if you want go one step closer to those machines they have different characters on keys with Ctrl which look like this:
http://atarionline.pl/cn/data/upimages/Fonty/ATARI.FNT.png
http://atarionline.pl/cn/data/upimages/Fonty%20C64/c64_lower.64c.png
http://atarionline.pl/cn/data/upimages/Fonty%20C64/c64_upper.64c.png

You can download this and more others font from:
http://atarionline.pl/v01/index.php?subaction=showfull&id=1236639234&archive=&start_from=&ucat=7&ct=poczatki
http://atarionline.pl/v01//index.php?subaction=showfull&id=1242399102&archive=&start_from=0&ucat=7&ct=poczatki

But this FNT files are tricky, because XL/XE and C64 keeping characters in memory in different order:

CPC and ZX:   digits - BIG - small - squares .... etc.
Atari:             digits - BIG - frames - small. .... thats it, rest is the same in inverse
C64:              small  - digits - BIG - frames.  .... rest is in inverse.
C64 upper:     BIG - digits - bars - frames.

ZX Spectrum have 6 different meaning on each key. It hard to make on CPC, but squares on digits keys and least one word on letters keys can be done with Ctrl. Q-PLOT, W-DRAW, E-REM, ... etc.    I did it in Basic    8BIT.BAS     on DSK.  RUN 30

Well, I'm lazy and I use JavaCPC's ROM-editor...
(I just need to edit the startup-message with a Hex-Editor)

[attach=2]

It can also import your FNT files from your DSK... (Did not test any special formats yet)
