CaH4e3 updated his site with the following message:
- CoolBoy 400-in-1 (Alt Version, 403 games)(Unl)[U][!]. HardWareMan once again delivered a new ROM, thanks a lot! He accidentally appears to have a new version of TeamEurope's cart released here 4th January. Previous version is older revision (internal signature of old version is "400 IN 1 zyx-8b2799", and new version is "400 IN 1 zyx-8b2922"), it has a lot of free space (about 700k). So this empty space was used in newer revision, three more new game hacks was added to the menu, so we now have 403-in-1 technically. There are many changes inside the newer ROM, but mostly this is shifted parts of various games, the rest of the games in list are identical to previous version.
Three new games is a title and sprite hacks of japanese Ninja Gaiden 3, Adventure Island 1 and 2.
