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:
