Magnificent result! Now loads of questions:
Shoot me!!! xDDDD
- Will it be possible later, that the ROM positions are flexible: ie: ROM_1 anywhere under position 16 and the other ROMs anwhere from 16 onwards?
Of course, only was a fast test, i only would have to add an header at the rest of game roms to the first rom would be able to identify them.
Even it would be possible to make a "game launcher" rom that autodetects every "game" rom in the upper positions (16-32) of MegaFlash, and you can choose which game runs

- Does it need BOOSTER to be intalled to work?
No, it doesn't need Booster, but it must not be incompatible, because i mark the extra game roms (the roms in the upper positions) how extension roms (the first byte need to be 2), because that the Booster and the firmware will not try to initialize them ... one advantage of extension roms is that i can use every byte of them except the first

- Does it copy itself to RAM or run from ROM.
Copy to RAM, usually the game has to be ready for being executed from rom and that it doesn't happen in the CPC, mainly because it's very normal to use self-modify code and fix these things are a hell

But for new games, it would be a great idea to give a rom option
- Are there games that would fit on a single ROM: Harrier Attack or other more simple games?
Yes, every game that we can crunch to 16000 byte or less (to give some space to the decrunch routine and the RSX to launch it), i'm going to try a few ones, i think that Manic Miner (or other of the first CPC games) could be a great candidate for being in one rom only.
- What method / tools do you use to convert the game?
Well, i downloaded the original game from
CPC Power, cracked the original using WinApe to make a more intelligent ram dump that the multiface

(although other idea could be to make a snapshot rom loader, jejeje), coded the game launcher and made a few 16 KBs chunks of the game dump for the roms.
I'd love to try and convert a few of my favourites.
Well, if you think that the procces is too complicated, tell me what games would you like to have and i will convert them for you
