So I'm looking at these ROM files in a Hex Editor, because I'd like to just show the game-name when I call |HELP from the Utopia rom.
To learn where this is located, I view the The Defend of Die ROM because it shows the game name fine.
But the Hex Editor only shows "DEFEND OR DI."....  where's the last E?

Seems to be the case with all ROMs. The last character of the name isn't there. What gives?

Steve Ansell did an amazing conversion of MUTANT MONTY recently... so here's a CPC ROM version of |MUTANTMONTY.

So, here's an overview of ROMs so far and the name they display in the list.

"Astro" display "HOLA" ?? What? Why? Why doesn't it display "Astro"?
"Axiens" displays "CLASSIC AXIENS".  Yay!  :)
"BoulderDash" displays "DASH"  why not "Boulderdash"?
"Defend or Die" displays "DEFEND OR DIE" yay!  :)
"Roland goes Digging" displays "ROLAND"  why not "Roland goes Digging"? Not enough room?
"Donkey Kong" displays "OCEAN"...  why not "Donkey Kong"?
"Fruity Frank" displays "Fruity Frank". Yay!  :)
"Killer Gorilla" displays "KG"  why not the full name "Killer Gorilla"?
"Hunchback" for some reason displays "FECK"
"Classic Invaders" displays "QWERTY"..  ? Why?
"Mutant Monty" displays "SP"
"Manic Miner" displays "GIRLS"....
"Tempest" displays "THEE"
"Thrust" displays "ARSE"
and "Trashman" displays "DEAD".

These are the names I see in the ROM list in Arnold Emulator, so I'm assuming it's the same names that'll show up if using Utopia ROM |HELP command.
Why not display the actual game name in such a list? It sure would be a lot more helpful in my opinion.

EDIT: Yup, the same names show up with the Utopia |HELP command. This is not that great mates. It should really display the actual game name.

Ok, try |SPACEMANIA. See if the name for this one is any better.
I can always rebuild the other games to fit any naming convention, but it might take a day or two.

Yes. It says "Space Mania" which is perfect, because it's the title of the game.  :)

Yes, because you put the title of the game. (I would prefer if it was written "Classic Axiens" instead of "CLASSIC AXIENS" though, but that's just me being picky).  ;)

Seems to be the case with all ROMs. The last character of the name isn't there. What gives?
The last character of the name has bit 7 set to 1 (ascii value + 128). This indicates it is the last character of the string.

Some other languages have an additional character to indicate the end. C uses NUL (0) for the end. CP/M often uses "$" as the end.

The "name" of the ROM which is seen in UTOPIA and Arnold emulator is always the first string.

The others are the commands available.

The v1.1 part is taken from the header, it's the second and third byte I think with a "v" before it.

You can easily change that by usage of an HEX editor, use ROManager to tell you the new checksum (use HEX Editor again to put checksum in ROM file).

Super Sleuth
Nuclear Heist
Street Machine
Atlantis
Star firebird
Gauntlet
5th Axis
Bruce Lee <-- that's almost a must. How did we miss that so far?
Frostbyte
Gilligans Gold
Kungfu Master
Light Force
Tapper

...but I could go on...... (and I probably will!)  :)
