That logic doesn't make any sense.Your argument that the cart doesn't behave like a 100% real cart could be flipped to say the Unibios isn't a 100% bios because it doesn't work with the multi cart. It's just silly.
I’m sorry, but I don’t agree with you, I think you’re mixing things up, i.e. Software and Hardware.
Unibios is a software (which runs aside games) and it’s expected to run without bugs on original hardware or anything behaving 100% like the original hardware. i.e. Unibios runs on accurate software emulators with the same results as real hardware and this is a proof of the accuracy of these emulators.
A flashcart is a hardware emulator and, as any emulator, is expected, given the same inputs, to provide the same outputs as the original emulated hardware. It doesn’t matter if these inputs are provided by a real hardware, a logical analyzer or some other hardware emulator, what matters is same input=same output as a real cart.
It’s not an issue of what is designed for what… it’s about which functional behavior you’re emulating. Original carts in this case.
I own a Super NT (a FPGA SNES Hardware Emulator) and if an original game runs on it or on a SuperCIC modded SNES, but the same game doesn’t work on the same setup with a SD2SNES (a SNES Flashcart), Ikari (SD2SNES designer) investigates the issue and nobody in his forum or Discord chat writes “you WANT” with caps lock, drama or anything else. I’m sure this is the same approach followed by DarkSoft (i.e. he said somewhere, without raising any drama, that he will disable the flashcart MVS/AES feature in presence of Unibios)… I just don’t get this personalization of all issues, this is a technical forum, not a football fan forum.
