Re: Fixing timing, and new features

I removed that chunk of commented out code since it seemed to be something abandoned, and there was no documentation by it how to use it, what it does, and whether it relies on anything else, so I figured it might not even work already. It should have been made a feature accessible by a command line...

Re: Get that emu faster

Fasten your seatbelts! https://github.com/Jubatian/uzebox/tree/uzem140-hacks This thing might even outdo CunningFellow's branch, so might probably fly even without his changes! :) (Obviously, in the longer run, combine and smile) I was a bit shocked by the end result, four changes, which individuall...

Re: Get that emu faster

I am looking at the pre-decoding branch done by CunningFellow. The biggest hit in performance (that is where the most could be gained) in my opinion could hide along these lines: const u8 opNum = insnDecoded.opNum; const u8 arg1_8 = insnDecoded.arg1; const s16 arg2_8 = insnDecoded.arg2; This is on t...

Re: Too many stuff going on

I just got an idea which will likely ramp up performance especially for multi-cycle instructions in my branch. Actually very simple thing, and it doesn't even wreck anything of the clean-up, as far as I remember the assembly output, it should deliver a notable kick. Should... I will see what happens...

Re: Could anyone help me acquiring an Uzebox?

No need to hurry :) Living in a PAL region with no modern television (which might accept NTSC signal) I need a complete solution including some (not too large !!!) display, like I mentioned in the other thread . If you also have to order the board and stuff from Adafruit, the 7" mini TV from th...

Could anyone help me acquiring an Uzebox?

So the dilemma is here. I wish to do stuff on this nifty little game console, but lets face it: I am no electrical engineer, and that's only part of a bigger problem. In short: Could somebody spare some time to solder an Uzebox for me, and send it me in a manner I can receive it safe and sound? (Of ...

Re: Get that emu faster

No it doesn't because the pre-decoder still uses 8-bit types internally. ;) I know, but that's still pretty much enough to break stuff in subtle manners. It makes things only worse that the variables are global to the exec function, so you can only change their type to all the instructions, so you ...

Re: Merging with Git without a loss of sanity

Text editor (mcedit), removing the conflict markers by hand :) But essentially the setup for complex situations is the same you describe with meld: I have three terminals open side-by-side with mcedit showing the respective versions.

Re: Get that emu faster

I though about doing the same in my run of performance optimizations, but I discarded it. This is far from being a trivial change, and I have experience on it (my RRPGE emulator's 16 bit CPU's ALU is realized with 32+ bit unsigned integers). For most part it works, but there are a few instructions, ...

Gordian Tomb: awesomeness in a few kilobytes

Gordian Tomb is a Commodore 64 game, which is notable for me for its soundtrack. If you like the old breadbin, you should know about the HVSC , where you can get just about all the SIDs ever composed, be them demos, game soundtracks, whatever. This particular piece comes from Thomas Detert, and is e...
