Re: Gigatron ASIC?!?

This is a fantastic idea, I personally have no ASIC experience and my FPGA experience is starting to get rusty; but whatever I can help with I'm available to try and make this a reality. All the extra features you mentioned sound great to me, the only thing I would add, (seeing as this is effectivel...

Re: vCPU instruction frequency

And yes, the "pixel burst" OUT instruction (superimposing the first two bits for the sync and incrementing X to pass to next pixel) is by far the most used, since the gigatron is spending most of his time generating the physical VGA signal! Regarding the comparison will be very easy: I've done the ...

Re: Raspberry pi loader

Hi, everyone! I feel like I've joined so late in the game on all this fun! I finally got my Gigatron put together (felt like quite an accomplishment for me since when I started, I didn't even know how to solder! lol) Welcome and congratulations on getting the Gigatron up and running; it really is a...

Re: vCPU instruction frequency

It's extremely interesting actually, as PucMon's code was generated by a compiler and it's fascinating to see where the hot-spots are. What would be even more interesting would be to compare compiler generated vCPU to hand generated vCPU. DavidHK did something similar, but at the native instruction ...

Re: Invader

For the last invader, left to right is 3 pixels per frame, right to left is 2 pixels per frame, (just like the original), so it's usually a little easier to wait for right to left.

Under-clocking/using mode 0: I see you went to the Kirk-Kobayashi-Maru school for lessons :)

Re: Invader

Those games came out in a time where people had to put effort into writing very lean code, possibly using some dirty tricks as well. It's funny to see that the Gigatron requires you to take on that mindset again. This! This is exactly it and I personally think that we have only witnessed the tip of...
