I must be dumb but I cannot do anything. Let's take the example for Air Force delta :
I load track 30 in the Hex editor software, search for "048A1A5E" in all directions but the software does not find anything. I patched many games for wide screens with this software in the past and I never had any problem. What am I doing wrong ?

Awesome job TapamN! Just tried out Airforce Delta and it's working great!

Here's a pre-patched track30.iso for DreamShell users with optimized/shrunk GDIs:

Indeed. I went ahead and took the modified 1ST_READ.BIN file and built a .DCP patch to make things easier for others in the future. I also see that the pre-patched GDI is available in dubcity's thread, but I'm still going to share the standalone patch as an alternative option for others.

EDIT: Wow, a bunch of new patches too! I'll build DCPs for them as soon as I can.

Update: Use the latest update.

VGA patched track03 and track30 of the US TOSEC Airforce Delta dump. Working on GDEMU.

TapamN wrote:I think I found something that might fix for Hydro Thunder 1.020's spotty compatibility. It's not enabling interlacing, but it frequently slows the pixel clock from VGA speed to NTSC/PAL speed for a moment several times per second (maybe once per frame? not sure) while it changes the display size register. I'm not sure why it's changing it. Unpatched Hydro Thunder runs fine on everything I can test with, so I don't know if this actually fixes it, but it doesn't seem to break anything after patching, and in an emulator I can see that it stops toggling the clock speed. If you have problems with Hydro Thunder, check and see if this helps. This is only for the later 1.020 version, not 1.002. The game should still be NTSC compatible with this patch, unlike the others.

Code: Select all

RAM addr	Track37 addr
8c0963a4	22674F54	change 0b 43 to 09 00

Codebreaker:
0f0963a4
00000009
I gave this a try with DCDigital HW2 with MagiClock feature disabled (which fixes Hydro Thunder). I get a black screen in VGA mode, with the music playing, but cutting in and out every other second.
