First of all I would like to announce that my WonderSwan emulator is now called dualSwan - A much better name in my opinion.
Second, I want to show off my progress with some screenies. Layered tiles were implemented with FluBBa’s help - huge thanks flies to his direction!
The FPS you see on the screenshots are close to original results on HW. but since dualis refuses to emulate in full speed - add another ~6FPS to get the original results on real HW.
Low FPS on games occures because of a poor NEC CPU core implementation. Don’t you worry, it will be much better
