What specifically does the Arcade card add?

[Black Tiger]

The ACD card adds the potential for a whole new library of bad ass games. Along with the disappointment that only like 8 were made. Half of which being games that were already on other consoles to begin with. 

I know the question was tech related.

Sapphire and Itouryoden are pretty epic as far as exclusives go.

If I remember correctly, the ACD also has some additional math routines...

Just curious, but what is the viability of using the RAM in the ACD/SCD cards as work RAM instead of only storage? How is the read/write access time compared to the built-in RAM?

[nodtveidt]

IIRC, it's port-based rather than address-based, which would mean that it's going to be inconvenient to use for anything other than block copying.

Interesting. Thanks!

I know certain games that don't even have a arcade card logo on it decreases the loading times between scenes and such. An example would be Wizardry 3 and 4. One game people often miss when they talk about scd/acd is 3x3 Eyes and this video does a good job explaining that:
I wish there was a video comparing the supercd version of popful mail vs when using the arcade card...

I've tried a couple times to ro a Popful Mail comparison, but the game keeps crashing in ACD mode. I might try again after I get my future main PCE unit back from being modded. I was able to narrow down that the Arcade Card doesn't enhance the cinemas or reduce load times or frequency for the cinemas. So it might simpky eliminate some of the minor in-game loading. But that doesn't even seem worth the bicompatible branding. So maybe the in-game content is sonehow enhanced?

Remember Flash Hiders? IIRC the AC adds one win pose vocal sample to one character. Nothing else whatsoever. It might be extremely hard to find some of these differences.

I have no idea what it does in Gulliver Boy.
