Kega Fusion 3.64

[Chilly Willy]

There's been a lot of work by a couple people over at SpritesMind in figuring out EXACTLY how the YM2612 REALLY works. As far as I know, the only MD emulator to currently use those results is Regen. Snake has a number of changes he needs to make for his next update to Fusion... among them, changes I made him aware of concerning the 32X PWM audio. The only emulator to currently handle the 32X PWM correctly is Gens/GS r7 with my 32X PWM code patch applied. When I need to test my 32X code under emulation, that's what I normally use since I'm more concerned with the PWM than the FM.

Regen sounds just perfect with the filter at either 0.997(default) or 0.999 for a more CCAM sound. Shame it's filled with bugs and doesn't support the Sega CD .

[sheath]

Regen definitely sounds better than the last version of Fusion I heard, it just didn't have as good compatibility.

[Chilly Willy]

Yeah, hopefully Snake makes a 3.65 with the better FM and anything else mentioned.

Just cause everyone kept showing screenshots.

My fusion has no fullscreen resolution mode.

What operating system are you using? Mac OSX? I think that's the only one without a resolution option (because you shouldn't change the resolution on a mac, there's no advantage for something like an emulator).

There's only 2 reasons not to use the native screen resolution: CRTs and performance.
You don't have CRTs on the Mac and all the systems that support Leopard can easily run Kega (so performance is also a non issue). It's the same reason you don't have lower quality sound options, it's always max quality.

[evildragon]

You can use a CRT on the Mac, if it's a mini or Mac Pro.

I use a 27" LED cinema display though, so I can't use native resolutions, but I just wanted to show that it was in fact missing in some configurations.

Ok, I fixed it..I had to delete the 3.64 folder I had & download it again..works fine now

I'm not talking about that at all, I'm talking about the actual switch to fullscreen. On Mac OSX and Linux the switch is either instant or there's a smooth fadeout, on windows a ton of crap happens (you can see the desktop changing res and the screen going nuts) before the switch is finished. This is a windows problem not a driver problem. Happens with any card.

Weird, I never see that happening on my laptop, and I don't remember it happening on my old XP machine either. All that happens when I go to full-screen is that the desktop (and any non-minimized windows) blink out of existence to black and then the full-screen emulator display pops up. (albeit, old Fusion 3.60 -and earlier- makes things lag much more and the screen blinks a few times as it switches from 32 to 16-bit color mode -assuming you're not already in 16-bit color . . . sort of like how things go weird with 256 color windows applications -the desktop drops to 8-bit color too)

Nope, without the filter option it sounds like the direct output of the soundchips with no bugs. With the filter on it sounds like a bad model 2.

More like a good bad model 2. (ie one of the earlier models with semi-decent caps and additional filtering -not the really shitty ones with massive distortion problems)

Yeah, hopefully Snake makes a 3.65 with the better FM and anything else mentioned.

Upping the DAC limit to around 26 kHz would be nice too. (or offering a "HQ DAC" option or such)

In the end, there is not a single emulator (video utility) that outputs correctly the 15 kHz video modes used by the system (yes I am talking about onthe-fly switching between 320 and 256 modes). So for a 100% Genesis experience you do need the real system.

One will always require the original hardware for a 100% authentic gaming experience, but Genesis emulation is among the best and most supported out there. I'd like to see a Saturn emulator half as good as Fusion.

[ThugsRook]

Everytime I exit out of Fusion, it freaks my monitor out...like go to Black that Normal....I have a 1280x800 Ressolution screen

(KEGA uses 16bit color by default)
open Fusion.ini in Notepad ~ forth line down change to: ForceFullScreen32=1

With aspect correct enabled, this is emulated pretty well (as well as scaling can accomplish), but for many games I prefer leaving scaling off such that square pixels are always used (unlike real hardware) and pillarboxing is present in mode H32 (256 width).

There are a few games that are properly optimized for non-square NTSC (or, rarely, PAL) pixels, but a huge number appear to simply assume square pixels for everything, so it all looks "wrong" on real hardware (unless you manually adjust the TV/monitor to compensate) whereas unscaled square pixels look "right" on emulators. (so the experience can be better than on real hardware for those cases -this isn't limited to the MD either, but many systems including the SNES, SMS, NES, MSX, Neo Geo, and others -albeit Neo Geo is almost true square in NTSC anyway)

For games explicitly designed with non-square pixels in mind, it's obviously preferable to use real hardware or an emulator with aspect correct enabled.

This is also true of many old computer games with non-square displays (from mode 13H VGA to CGA/EGA stuff to Amiga to ST -A8 and C64, etc have more serious problems since emulators use 2x wide pixels by default-), albeit that can also often be corrected on the monitor end, especially for PCs. (aside from manually adjusting overscan, switching to 60 Hz for mode 13H -rather than the default 70 Hz- will result in very nearly square pixels on monitors at normal calibration, and also show letterbox boarders).
And, again, some games compensate for non-square pixels while others don't . . . and some do both. (some scenes corrected, some square . . . or sometimes a mix of both on-screen at once like 3D portions not corrected and 2D overlays corrected, or vice versa -the latter is much more common for games supporting variable resolutions, with 3D stuff catering to various pixel shapes but 2D overlays being unscaled . . . a problem that persists in some modern games even -and is especially obvious in games supporting both 4:3 and compressed 16:9 in SDTV)

I think many NES games were designed for the real "non-pillerboxed" display... Anyway, I think it does not look good when the display is not proper 4:3, even if the pixels are not perfect squares, it is how the real things display that graphics...

I wish there was a utility to switch between correct 15 kHz video modes on the fly (Mega Drive a good example) so that we could use emulators to full potential... it is definitale doable and I think someone (Advance MAME author not sure...) has already been into this

Many NES games have that problem too, though many also don't. (and many also have a mix of both)

Many things on many of those consoles looks wrong and distorted due to the way they display on normal TVs . . . and it's much worse for PAL in most cases. (the MD -in 320 wide H40 mode- would be among the exceptions since it's much closer to square in PAL than the NES/SMS -or similar- though still quite distorted -hence why sonic looks too short in PAL vs too tall in NTSC; the Amiga and ST would be much more extreme examples: they both look way too tall in NTSC -for square pixel art- but the Amiga is nearly square in PAL and the ST only slightly "too tall")

Virtually no monitors support 15 kHz (and few to no modern video cards support it natively either -discounting intpolation/scaling to SDTV resolutions), so the point would be moot.
