ISO Loader 0.6.x Beta

[Acey]

@swat

I've been using retrodream with sd adapter
Working good with some games and not so good with some
As expected via sd adapter(serial)

With my surprise upon testing the new atomiswave games
That were ported two out of five happen to work great kof has minor stage writing bug and high score bug but gameplay is perfect got to the end also samurai spirits works flawless gameplay speed is very fast and no skipping but stage starting glitches

I have been testing via 0.6.6 beta sd loader
Both games work on memory 0x8cfe0000 and 0x8cfe8000
I have setting sync on true also tested 8 and 16 but doesn't really look like it makes a difference in game does fix glitches but games run great

Apart from those two games others either refuse to go past excuteing or if they do they just go straight to black screen

I have just recently tested isoloader 0.6.9 and beta 2 on kof with same settings just doesn't go past excuting also same results with 0.6.9.10

I wonder what could have changed to make those games stop working?
Is my first question secondly is there anyway to look into how and why these two games I mentioned load and others refuse to?

Thanks for reading and sorry for long first post
