Why can’t certain games be patched to run in VGA?

Just an FYI - Aqua GT (PAL) works in vga. So does the KoF (JP) titles. That's what I use when my vga adapter is hooked up.

I have the GDI’s of Aqua GT and KOF DM 1999, ‘9 E, 2000, 2001 and 2002.

Or do you mean that the Jap versions of DM 1999 and ‘99 E do work with vga?

The last three only.

Yeah, but I heard that DM 1999 is the best of them all, dunno why exactly. Also Aqua GT is not as fun as Hydro Thunder…

So I’ll never be able to play it in vga then…

Just did some testing.

First off, I was wrong about it not working with my Naki VGA box. It seems to be working fine with it. Apparently the first time I tested it (which was a long time ago), my testing was flawed somehow. So yeah, works fine in VGA with both my Naki box and my Tomee VGA cable.

Also tested with an Etekcity VGA-to-HDMI converter (pictured below) and it worked fine with that as well.

The only issue is the menus which flicker occasionally (happens both with and without the HDMI converter), but it's not a big deal. No problems in the game itself as far as I can tell.

Here's a screenshot of it running through the HDMI adapter:

Could you help me understand then why I can’t make it work with my setup?

You'll need to replace your Altona box with one that can handle Hydro Thunder's wonky vga signal. mrneo240 swears by his portta converter/upscaler (discontinued model). Unfortunately, I don't have a link to a box guaranteed to work.

Yeah…sadly that’s not an option right now. Where I live importing this is expensive (since the adapters used by others aren’t easily available here). That’s why I don’t think I’ll be buying the composite hdmi adapter someone recommended

Then I would look for a used computer monitor with vga input on the cheap or possibility free locally. Then connect the retrobit vga cable directly into it.

Like I said, I do have a VGA input in an old hdtv that is at my parents house, but I don’t have any space where I live to put it. So that’s why I bought the hdmi converter a couple of years ago. So yeah, I might be locked out of HY in VGA

The problem can be solved but you cant expect cheap crap from china to solve it.. no one size fits all here..

The problem here is your converter we cant fix games to suit converters
