Help with and emulator

Hello:
I´m a 19 years old student of Zamora, a small town (60.000) of Spain. I´m studing Telecomunications in Valladolid, near Zamora. But the main reason of this email is that I´m writing a Sega Master System emulator also. I´m using the Marat´s Fauzullin Z80 Engine, althoug very modified by my. My emulator, called Calypso, is and idea of make a Nesticle for the SMS. The main object is in C++, and the GUI is also in C++. The SMS routines are in C and in assembler. The Z80 engine is in C. The emulator is capable of run Sonic The Hedgeog, the intro of several games, etc... but I have several BIG problems, and I decided to write here because yours probably had had the same problems, and know the solution. The main problem is that Sonic the hedgeog is out of sync. Explanation: when the game starts, the Sonic make rare things, like fall down whitout any obstacle, kill whitout any monster, etc... The game is unplayable. I think that the problem could be associated whith the values of Lines in the VBlank period of the number of opcodes per scanline. Other games, like Sonic II, make a loop, expecting something that don´t occur (I´ve a debbuguer). Could you help me? Did you have the same problem? Could this be relationed with the sprite colision detection? Thank you by reading this mail. And sorry by my poor english. I didn´t pass my June examn :(. Thanks. My email direction is: jdelmen@calimocho.tel.uva.es if the above don´t work: jdelmen@ribera.tel.uva.es |
