Re: WIP: Tetris + any GCL tips?
2. The blocks are 4 pixels in height, and the first line looks the same as the fourth. You can reorganise the video indirection table such that every fourth line is a copy of the the 1st. With that you need to address fewer bytes. Judging by the fast scrolling of the title image, you have already m...

Re: WIP: Tetris + any GCL tips?
Aah, this is interesting and explains what I was seeing before I think? (it's late, so I've not thought through this properly...) I worked around this by padding all pages out with zeros, so I guess it would consistently execute harmless code - for me, this gives consistent behaviour on hardware and...

Re: WIP: Tetris + any GCL tips?
Actually, came up with an idea at lunch after realising that there are 2 spare bits for every pixel on the screen - very handy, hopefully I can get the movement smooth

Re: WIP: Tetris + any GCL tips?
I implemented what I suggested, but of course it doesn't stop the flickering when the piece moves (though the code is tidier for it, so it's a net benefit). Sped up line clearing to the point I think it's acceptable too. I think if I want to have flicker-less piece moving, I'll need to change how co...

Re: Double your RAM:
Thanks for this, I was going to get to this at some point, so great to have some nice easy-to-follow instructions for it! Just a note, the pictures aren't showing for me - might be worth replacing with imgur links or something? I guess this might be a phpBB teething issue.

Re: WIP: Tetris + any GCL tips?
Great answers, thanks both :) I'll try briefly to see if I can time the collision/control check to happen quickly enough to be able to blank and draw the piece, but otherwise I think I'll do what I was suggesting and just check possible collisions on moving. I want to get scoring and progression in ...

WIP: Tetris + any GCL tips?
I've been working on Tetris for the Gigatron (On emulator: https://youtu.be/BATJq6sy6eM On device: https://youtu.be/6YYSNdGqg_0) and it's going ok so far, all the basic building blocks are there now (excuse the pun), and it's mostly a case of polish. The game is currently about 6k, which is mostly t...
