Anyhow, last night i did a forum search for "scaling", "phantom", etc., looking for answers to these particular scaling issues. After hours of reading, i've come up with some conclusions:
1.) Both the P1 and SMVSII have consistently inconsistent scaling issues depending on factors such as board revision, cart, and converter build. Everyone has a different opinion on the problem. Personally, after having read everything, i think the problem depends on multiple factors listed above and not just one. Pin-pointing the exact working combination is not possible.
2.) Neo Alec has beat this topic to death, buried it, dug it up, and fucked its ass.
But really, i can understand your point of view. Not to sound like a douche, but this rig cost me around a grand and i'm still not playing in perfection, whereas a considerably cheaper cmvs/supergun rig would. In my eyes, neither way is perfect. I have always wanted an AES in its sleek console form playing the actual games rather than a CMVS, in its rather home-made appearance, doing the same..but obviously one trades appearance for slightly better compatibility.
To each his own.
