Added Scale2x and Eagle GPU filters.

Scale2x: 8 TEV stages, 1 indirect lookup
Eagle: 4 TEV stages, 3 indirect lookups

Just curious, what do you call the default zoom filter?

Extrems · Post by **Extrems** » Sat Oct 03, 2015 12:23 pm

Oversampling, the best of point and linear sampling.

I finally performed the HDMI mod on my GC. Here is GBI on my 50" plasma (GBI loaded off of my Max Drive Pro) zoomed at 2.5X:

Hello guys, Just registered to post in this thread.

First of all I just want to say that GBI is AMAZING, I'm using the LL version on a Sony Wega 25 CRT, with S-VIDEO, and the games looks great, ( I tried using the ULL , but got only black and white colors

)

Also I want to ask for your help, I'm using the .iso that darcagn compiled in June, and it works fantastic, But, I wanted to burn the latest .dol, and so far I've wasted 2 minidvds

, I used GC Bootable disk GUI for the first one, and then I downloaded some tools for making a swiss bootable disk, replaced the dol for the gbi LL one and renamed it bootldr.dol, clicked a .bat, and burned the iso, same problem (GC gets stuck at logo, and the controller beggins to rumble).

Can anyone help me with that? thanks in advance.

EDIT: I managed to get a working iso, using this:

The download page seems to be broken right now.

Seems to be working and there's a new version too?

Thanks for the new version! When I get a chance I'll make a bootable iso for this.

Is adding scanlines possible?

This small update adds 2 trivial filters: Scan2x and Normal2x.

XC-3730C · Post by **XC-3730C** » Fri Oct 16, 2015 3:22 pm

Nice! Anyone have any screenshots of scanlines on an LCD or plasma screen?

How do I enable scanlines? I downloaded gbi-20151014. I would also want to know how to enable 240p if possible.

*edit*

I finally got an HDMI to VGA active adapter. It came with a USB cable for power (5V), and I connected it to a USB charger.

your link in the OP is downloading the build from 10/14

How do I enable scanlines? Is there a 240p option like Swiss and the Gameboy Player disc?

480i/p is preferred in the standard version.

XC-3730C · Post by **XC-3730C** » Thu Oct 22, 2015 12:03 am

240p is much better than 480i/p. Look at the Startup Disc running at 240P via Swiss 240p option and see what I mean:

Extrems · Post by **Extrems** » Thu Oct 22, 2015 12:05 am

Thanks, I wrote the video patches for Swiss.

XC-3730C · Post by **XC-3730C** » Thu Oct 22, 2015 12:06 am

I guess I could run GBI through Swiss and force 240p.

novenary · Post by **novenary** » Thu Oct 22, 2015 8:14 am

Doesn't work that way, homebrew and games are two different things. If you run it through Swiss you can change the GBI options though.

There is no need for scanlines in the 240p version on a CRT as real scanlines will be displayed by the CRT, like your screenshot shows.
If you are using an LCD screen 480p/480i with scanlines settings turned on through Swiss is your best option not 240p.

Just thought I'd throw in a warning for those burning the ISOs of GBI: some burners appear to have a minimum ISO size requirement to burn successfully.

This evening I installed a Xeno-GC in my gamecube and adjusted the drive pot, and then burned an ISO of the gameboy player disc (using TDK 4x mini DVD-R) to test things out: it worked fine.

I then tried to burn GBI, and ended up making three coasters. First I tried to use the batch script in the "homebrew_disc" package, burned it with imgburn, got a failed burn (imgburn won't even start verifying it, gamecube makes funny noises with it). Then I tried doing the same thing again but writing the commands out by hand using the gc-forever wiki instructions. Same result. Finally, I tried using the ULL ISO file posted earlier in this thread and just burned that directly. Same result.

Finally, I started to clue in that there might be something strange going on because of the ISOs being so tiny, so I threw a random one gigabyte file into the disc folder before making the ISO (resulting in a 1.03GB ISO), and that burned perfectly.

I probably don't need to use a one gig file to get the ISO to burn (maybe 100MB would do, for example), but it worked, and these mini DVDs are too expensive to do much experimentation with. I thought I'd let people know as a cautionary tale, in case they have similar problems: some drives just can't burn tiny ISOs.

For reference, my burner is an ASUS BW-12B1ST, which is a bluray burner.

So this is great and all, but I have a few issues with it. Firstly, ULL mode works on my display, only it develops this sort of weird tearing effect at the top of the screen when moving at high speed, like everything seems wavy. LL mode doesn't work at all for me, my display just says "HDMI out of range". Normal mode works fine, but the brightness is way off, like, way too bright, with no way to adjust it.

You got unlucky.

Xaranar wrote:LL mode doesn't work at all for me, my display just says "HDMI out of range".

GBI ULL has a 480p mode for HDTV compatibility, unlike GBI LL.

It can't be made darker without losing shades or throwing out color accuracy, the bitdepth is too limited.

Xaranar · Post by **Xaranar** » Tue Oct 27, 2015 8:27 am

Okay so if I enable the line doubler on 240p mode in GCVideo, LL mode works flawlessly. Thanks for all your hard work on this, btw. I'd love to know, though, why is the brightness correct on LL and ULL mode, but too bright in normal mode?

The low latency versions just throw up the pixels on the screen without any transformation.
The standard version simulates a DS or a GBA in daylight.

jayare · Post by **jayare** » Fri Oct 30, 2015 7:33 pm

Is there a way to change the aspect ratio?
I know this would make it incorrect, but on CRTs, it would make pixels a bit more visible.
For example, the SNES and its Super GameBoy display a 256x224 image that fills up the display area on the TV, but because of that, objects appear a bit "fatter" or wider.
The GameBoy Player seems to be doing something similar to 320x224 image (or at least that proportion), so there's more pixels wide, but the image becomes compressed horizontally because of this and objects don't look "fat" like in SNES. Sure, it's correct, but it's less visible. Just wish there was an option.
I think GBA games are supposed to almost reach the edges of the TV to have the same aspect ratio as SNES games did.

Bottom line is, I want an option to make the games have the same aspect ratio as they do on SuperGameBoy. Is this possible?

(I use the LL version)
