It's sucks. I've sent the source code to Rafael, perhaps he can help me with that.

Edit : Here's another bug fix version :

There are many unused bytes of RAM in VDC, addresses like 003h,007h,00Bh,00Fh (last bytes of each sprite control registers) etc...
I tried to write and read on them but not return the value. Can I use them on real hardware? I don't see why not... I'm guessing it's an emulator issue.

For unused VDC address there is no actual RAM in the VDC chip, so you can write anything to it but you can not read it back.
You have to be careful with writing data to some unused addresses, because they might actually be mirrors of other addresses (for example: the used addresses of 0A0h to 0AAh can also be accessed with 0B0h to 0BAh).

Score bug seems to be fixed on PAL and NTSC real hardware.

Thanks to clarify.

Finally!  Cheesy
Unless other bug appear, I would say this game is done.
Thanks everyone for feedbacks and beta testing Smiley

Hi people, here's the PAL version (and a bug fix on NTSC version).

EDIT: ROM UPDATED - 08/06/2014

-Bug fixes
-Longer gameplay time (99 game sec. = 2 min.)
-Dark gray crosses - looks better than white crosses due flicker

Thanks to Rafael and Tim for NTSC beta testers on real hardware.
Thanks MARC for PAL beta tester on real hardware
