Ketsui dumpato? :), Magari si, magari no... :)

Lol, giocarci nel mame costa come comprarsi la scheda .

Honestly, from what i can tell, the asic doesn't do much in the way of providing anything except protection to the game. On boot, the game expects 3 values supplied from the asic (and is easy to bypass). In game, it reads 2 more values (frequently) that are calculated in the 68k and the asic and compared (it is easy to bypass this as well). Lastly, the 68k will read 2 values from the asic, these values are scrambled around a bit by the 68k and used as addresses to read/write to (I'm fairly certain this is related to the sprite issues in the game). I have dumps of 3 revisions of the program rom, only the oldest one gets far, as the newer ones seem to actually check the values I'm using for the last bit of the protection (I think).

As for the status of the game, I think it is as far as I can get it. I'm going to pass it back off to XingXing and see if he has any more luck.
Right now, it is fairly playable, but there are random freezes, some sprite issues (positioning mostly), and the coin input is not read, so coins have to be inserted via the test button.

Va in fullspeed e l'audio è ok(nella descrizione spiega che è stato il recording video a rendere lento il tutto)
Qui il processo dei proiettili e nemici si comporta in modo diverso rispetto Shit Storm.

HOLYSHIT
quindi riusciremo a giocarlo presto o tardi?

Se XingXing riesce a blackboxarlo probabilmente sarà giocabile molto presto, altrimenti rimarrà come DDP2.

ma DDP2 non se lo sarebbe giocato nessuno comumunque *chinkface*

As it is, we (the FBA team), have not been contacted or asked not to work on any games at all. However, that being said, there are two reasons for the driver to remain private (at least for a while), the first being that the MAME team would prefer this not be added. FBA contains enough code from MAME that it could almost be considered a derivative build and as such, we need to respect them and their license as we expect others who use our sources to do the same. The second reason being that one of the members of the FBA team has a young family, while it wouldn't be a big deal for me to get sued (I'm childless and poor lol), I think even the possibility of legal action should be avoided to protect the wellbeing of that family.

I know it sucks and I would really rather make everything public (I'm a firm believer in open source, open ideas, open information, etc), this is just one of those times in which my feelings are not important.

I will keep working on this (and any other Cave/PGM game that is shared with me) and try to perfect the simulation/emulation so that when the driver can be made public, it will be worth the wait.
