So I have weird ideas from time to time.

I was thinking wouldn't be cool to have hardware compression on the genesis.

Question is what is the bus speed, and how fast would a chip need to feed data?

This chip pretty much would act as a memory controller, the 1st Mega Byte would just pass through ...

Dont know if this is ideal for what your doing, but how about using z80 ram for 2 buffers?, it means you have to use 68k to move it though, thats what I did for my adpcm demo.

I could kick myself for this. I left this pc back in England, when I moved to the USA.

So in England I had the megapc, it was basically a 386 motherboard, with an isa card which contained an adlib card/megadrive unit, with a cartridge slot on the front. The monitor that came with it had a special ...

27 (hail from the UK but living in the US), Work as server watcher and web page lackey (color/fonts/data needs to be changed etc..)

Do some development work in what ever language of the day it is.

So I'm thinking about another project that I will never write, but since its still in my head and formulating other ideas with it I figured I post it just to what the scene thinks. (maybe someone can use this and since I've typed it hopefully my brain will go back to thinking about other matters ...

It outlines the opcodes and is quite informative with regards to possible gotchas when coding a cpu emu. Zero page being the obvious one.

I would think the emu would want to have both an interpreted mode as well as a dynamic mode ...

I was working on a huffman based compression library a few years back (Which I never got around to finishing *gasp surprise*)

And was wonder if anyone would like it? (Plus that would give me motivation to actually finish it.)

It uses 3 trees one for the uncompressed literals, one for the lengths ...

Its funny you mention making a nes|sms emulator because I was thinking something similar just the other day, maybe even a gameboy emulator?

For the CPU emulation, perhaps doing some kind of dynamic re-compilation?? as that would definitely help with the speed plus you could utilize the 68k flags ...
