Sega Dreamcast NBA 2K1 and NBA 2K2 are not working properly on Recalbox 7.2

I have BIOS files and some games work perfect. But this two freeze after some play (even in practice mode).
Also NBA Live games (2001, 2003) freeze at the main menu screen on Playstation emulator (FIFA 2005 working just fine!).
Is there any good 3D basketball game working on Recalbox?

@helcril check your roms.
Look for a redump psx romset, and get your games from this romset. You can also find them in .chd format.

@Scavy, Alas this does not work. Redump version have the same problem freezing on the main menu.
Have you any suggestions on the Dreamcast issue?

[Scavy]

@helcril i want to say, if all other games work fine (on PSX on Dreamcast), that may mean these dumps are not a total success. If the game dump is the origin of the problem, nobody can do anything, except proposing a better dump.

[helcril]

@Scavy Ok, but why only NBA Live games on PSX? And this is not only my problem, have seen thread here on the forum from other guy. I tried different ones (2000, 2001, 2003) from different sources. Also I have found that NFL 2K1 on Dreamcast freezes too, like NBA 2K games. So I think maybe problem is not with game roms, but with emulator or system software?

@helcril do you have problems with other games (all games, not only NBA) on the emulators you use ?

[helcril]

@scavy well, there are some problems with some games (slowdown issues on PSX and N64), but not critical ones like with NBA games. I just want to play good 3D basketball game, and can not find one.

@helcril well i dunno any good basketball game ^^ try to check on the net

Update:
I found one more disc images from another source for NBA in .gdi format, converted them to .chd and it doesn't help at all. I think this is some compatibility issues. Also I can access an emulator menu when the games freeze. Can anyone help??
