Any news about this remake?

Great news! 

I'm excited with this project!

Can't wait to play it on my MSX2

I know, I know I'll use my MSX1 instead

I'm almost changing my mind about using mirrored tiles which has a big impact on the GnG game. My main issue is that my favorite MSX CX5M does not support it correctly. And if I can't run the game on my favorite MSX I need to think of alternative ways of designing the game. But until I have a good solution the project is somewhat on a hold.

IMHO you should use mirrored modes
Think to msxdev competition:

the rules say :

"VDP: TMS9918/TMS9928 or compatible video processor"

and the T6950 is not compatible with the TMS9918/TMS9928 processors
because only the TMS's allow mirrored modes
 

I'm in no way related to the MSXDEV TEAM, but AFAIK the rules try to state that the game should work in *ANY* MSX machine. Therefore, if the mirrored tiles is an undocumented feature of the TMS, it cannot be asumed as a part of the MSX standard. Other MSX(1) machines use VDPs that do not support this mode, but they are certified MSX machines.

For MSX2 and higher there isn't any problem, 'cause all V9938/V9958 do support mirroring.

@Dvik: if using vdp tricks is not a clean job, why not halfing frame rate (25/30 fps) and scrolling at 2pix per frame?.
I've built some demo on disk and if you want i can send you a quick and dirty example of the scrolling to give you an idea.

In this way you can gain:
- two independent char sets (but you need to reduce the height of the game area from 160 to 128, not a big problem i think), this allow you more freedom in design of charsets.
Actually, using the bitmap you've used for GNG demo i see only 80 different patterns on each frame, and you do not use at all color attributes. this means that you can blit the entire pattern table with 640bytes only.
- the smoothness does not suffer from this and you can split CPU power in two frames.
- all msxes (included you beloved  can run safely this sw)

If you want to take a look of a quick demo tell me, i've send you a .dsk with the binary...
