Take a look at one of these walkthroughs.
The Nicalis ports run faster, you're probably used to those. Enable the "CS+ Speed" setting in the config menu for something similar.
SRAM is malfunctioning, or not emulated properly. Check COMPATIBILITY.md for a list of tested carts and emulators.
If you encounter something that is obviously a glitch or bug, then I would like to hear about it. However, please do not open issues with minor discrepancies for the sake of "accuracy". If accuracy is your main concern, that is what CSE2 is for.
If you can't reproduce in the latest release, don't report it. The save data for version 0.5.0 onwards are all compatible with each other.
I may add your language if you have a translated PC version available, but no more feature requests. I want to release 1.0 and be done.
No. Pixel probably doesn't even know it exists.

Feel free to make carts for yourself or friends, but do not sell them.
It's a scam. Demand your money back.
Yes, just give credit. Check the license.
No.
