Kof2003 transparencies

[Robert]

I've noticed on the original kof2003, the power bars of the inactive players are dotted and are semi-transparent. On all the other versions, all the bars are solid.

 

What does it look like on a real machine? In other words which way is correct?

[Agozer]

AFAIK, the power bars are transparent, and the transparencies are handled by the custom BIOS.

 

I have Nebula transparency tables to correct this shortcoming.

I have bootleg version with hacked c7 and c8 roms, and it works fine under Nebula

The Semi-transparent ones are correct.

Um The MVS does not have the custom BIOS yet it still has transparencies.

I have a bootleg set that usess the extracted S rom data from the C roms and it has transparencies and it does not use the custom bios.

 

( The C roms are not hacked )

semi-transparent is as good as can be expected from NEO-GEO hardware. for example, if you take the decrypted text layer (512KB) from either svcchaos or kof2003 and split it into 128KB segments you will notice that the lifebars in kof2003 and timer block in svcchaos are solid in some segments and opaque in others. the semi-transparent effect is accomplished by cycling through these segments rapidly turning the relevant pixels on and off. amazed PLAYMORE opted to develop these titles for soon to be archaic hardware. to make a long story short they're as intended.
