Gameboy Advance RGB NTSC

[blizzz]

How do you even set this to 240p? When I start it from the SD Loader it says 288p50, but it seems to be 576i and is rather blurry. Is there a way to start .dol files in swiss with arguments?

I also wonder how the framerate conversion works. Does it just blur frames together?

Hmmm, Extrems said in the thread that 240p was the default mode... There is an argument you put in for NTSC or PAL, I'd assumed there was an .ini file or something. I'll check it out.

Hmmm, 2-3 frames of lag is awfully high. The stutter is barely noticeable to me in 240p, I think I'll stick with the original disc.

The original disc has to have at least 2 frames of lag anyway, though, because I can feel it on a CRT.

[ZellSF]

The original disc is pretty bad, so I'm wondering if 2-3 frames really is that much more than it.

He says the hardware is capable of displaying the image basically instantly without the framerate conversion, but the Gameboy Player disc quite obviously isn't actually doing that.

Still not worth it to buy a GBA player (or a GC) imo.

Do you think it's that much? I recently played through Oracle Of Ages. I started using my Retron 5 on a plasma TV and there was so much lag, it was almost unplayable; Anything that relied on reaction time, like jumping across holes, or playing any shooting game was impossible. Once I switched to the Game Boy Player (original disc, booted in 240p via Swiss) on my NEC XM29, it seemed fine. I played a bit on my GBC and GBA as well and the GBP seemed very close to the handhelds.

I realize that's all subjective testing, but during the hours of gameplay, I would switch between all the devices I mentioned above and the difference was absolutely noticeable.

[ZellSF]

Feels like 2-3 to me too, it does not surprise me that the Retron 5 is much worse though (and a plasma adds 2-3 frames of lag by itself).

I would definitely prefer the input latency of a PC emulator over the Gameboy Player on a CRT.

I don't have the means to measure it, but I figure that if I can actually feel the difference, then it's gotta be 2+ frames because, as much as I like to talk up my ability , I don't think I'm godlike enough to clearly notice a difference smaller than that.

[RGB0b]

LOL, fair. After using Artemio's 240p test suite for a lot of testing, I found that I usually notice lag around 4 frames for games that really rely on response time. It's probably more like 5 or 6 for games with slower action. If the GBP really has only 2-3, then I might not notice at all for some games.

After updating Swiss I can set Swiss to 480i and the Game Boy Interface boots in 240p now. The framerate may be smooth now, but it does indeed blend frames together which creates some nasty motion blur. Though you could argue that the original GBA also had motion blur on its screen. Overall I'm not quite happy with either solution.

It looks the same for me at 2x zoom, the only difference is that you get a black border around the screen. Were there any problems with the original disc at 240p?

Apologies, I can't seem to find any information, has there been a new update to swiss to fix hz issues resulting in stuttering gameplay on the gbp recently?

[blizzz]

No, the problem I had was that I couldn't set Swiss to 60Hz with the version I was running. Or maybe I just selected the wrong option. GBI selects the framerate you were running in Swiss, so I got 576i instead of 240p. I updated Swiss, selected 480i in Swiss and now GBI starts in 240p. GBI solves the stutter by blending frames and thus creating motion blur, the original GBP software still has slight stutter.

It's a new alternative to the GBP boot disc that was just released; Swiss is needed to boot it properly afaik, but it's not an update to the original GBP software.

[Einzelherz]

Forgive me for forgetting what this thread's been about, but is it using a PAL GCN for its RGB out with NTSC discs?

[blizzz]

It's about playing GBA games in 240p RGB with the GameBoy Player accessory for the GCN.

It's about playing GBA games in 240p RGB with the GameBoy Player accessory for the GCN.

So it's strictly a PAL discussion.

[blizzz]

If you want RGB from the Gamecube you need a PAL console, yes. But S-Video from an NTSC Cube is fine too.

Game Boy Interface was updated this week to add low latency output modes.

• Added low latency (buffered) version with 243p59.8261 video mode.
• Added ultra-low latency (unbuffered) version with experimental 243p59.7276 video mode.
• Changed all 60 Hz modes to have 486 active lines.

Haven't tried it yet, but it sounds promising.

So which one of those is the actual GBA refresh rate? I think there's a chance my PVM could display both.

[Xan]

59.73 Hz sounds like it. Should be fine on a CRT, might not be so great on other displays.

Maybe a Freesync display could handle it too? I would hope so, but there's also the possibility that they require standard timings when not using displayport + freesync capable video card.

Does this need a disc in the drive, or is it enough to just start the file from that media launcher?

[Arasoi]

[BazookaBen]

This particular program is a replacement for the disc, you just need an action replay for loading off an SD card or similar, and load up the DOL file.

So this: http://us.codejunkies.com/products/gcnw ... 00589.aspx

plus a GB player is all I need to try this out? Just making 100% sure before I buy.

[Thomago]

Yes.

[BazookaBen]

Sweet. How long is shipping to East Coast US from Code Junkies? Are they UK only?

[Xan]

But the earlier 240p Swiss solution needed the disc still in the drive, didn't it? And it still had the stutter every few seconds, while this doesn't in the "ultra-low latency" mode? Really seems a nice improvement then, hopefully they can work out the sound issues.
