How can I patch Ikaruga to 60Hz?

[Yod@]

Any idea how I might be able to patch Ikaruga to play at 60Hz on a PAL DC?

The standard patch doesn't work :(

Thanks :)

[Megalexxx]

Is it out already ???
Who did the release ?

[Yod@]

Yeah, I downloaded it this morning (believe it or not it's only a 20Mb dl). The nfo says it was released by W00T (never heard of them) but it definitely works. Only problem is, as I said, that it runs at 50Hz on a PAL machine, and the standard patch doesn't work (I also tried the Pal Patcher util with all the other patches and none of them work either).

Am I allowed to post here which newsgroup I got it off??

[Megalexxx]

I've just burnt it, it's coooool. :)

It works fine on my PAL DC. You can't remove borders, since they are on original game...

[Yod@]

Trust me, it's running in 50Hz (my tv's display tells me). The borders are there top and bottom on a horizontal tv, or at the sides on a rotated tv (like i'm using).

I suppose we'll just have to wait and see if any groups can release a specific patch for it. I'll just try and pick up a 2nd-hand US/JAP Dreamcast somewhere.

Thanks anyway, have fun with it.

If you don't care about wasting 1 CD, try this :
_ open Ikaruga image with an hex editor
_ look for "0B 42 09 00 03 88 04 8B"
_ replace it by "0B 42 09 00 03 88 09 00"
_ burn it and test it
_ tell me if it works :)

[Yod@]

Megalexxx: I tried it, but I can't find that particular hex pattern in the .cdi. Do you have any others I can try? I don't mind wasting CD-Rs... :)

Thanks a lot

[Megalexxx]

That's strange : I found it in 1st_read.bin. You should find it in the image...
I'll try tonight and let you know.

[Megalexxx]

Sorry, you have to look for "0B 42 09 00 03 88 04 8F"

[Yod@]

I just tried it, but it's still 50Hz :(

Any ideas, or should I give up? ;)

Thanks for your help Megalexxx.

[Megalexxx]

Hmmm...
If I find some news somewhere, I'll let you know.
Maybe someone will release a patch.

[Yod@]

Ok, thanks Megalexxx.
I'll post here if I DO find anything that works.

Hi Megalexxx, just wondered if you had any other 60 hz fixes for PAL DC games? I have a few old ones I'd like running at 60hz.
Also what Hex editor do you use to apply these fixes?

Thanks for any info...........

[Yod@]

Slipperchin: for most games which run at 50Hz on a PAL DC, you can use a hex editor to search for:
01 E4 03 A0 02 E4 01 A0 03
and replace it with
00 E4 03 A0 00 E4 01 A0 00

Doesn't work for these though:
Surf Rocket Racers
Maximum Pool
Sno Cross Championship Racing
Hidden + Dangerous
Quake 1
Midway Greatest Arcade Hits
Wild Metal
Bust a Move 4
Virtua fighter 3tb
Rainbow 6
Urban Chaos
Sonic Shuffle
Railroad Tycoon 2
NBA 2K1
Armada
UnderCover A.D.2025 Kei
Ikaruga
And probably some others as well.....

I use a hex editor called Hedit.

[Megalexxx]

This is one of the hexa string my PAL patcher looks for.
Ikaruga doesn't contain it.

[SlipperChin]

Cheers Yod@

I'll try that out.

I think I used Hedit before, so I'll have a look for it.

Again Thanks... :)

Yep, that's why I put Ikaruga in the list of games it doesn't work with ;)

Another question: how do I make Ikaruga a non-boot disc to try with other boot discs (e.g. Utopia)? Do I have to copy all the files, unscramble the 1ST_READ.BIN and make an IP.BIN file? How do I get an IP.BIN file off the original self-boot image?

[Megalexxx]

You can take any ip.bin, but be sure "1st file read" is set to 1st_read.bin. I don't think you need to unscramble it. Just binhack it with LBA = 0.

[Yod@]

OK, I had a go but it doesn't work - the Utopia disc reads it, then it changes to the screen with the spinning disc but it just hangs. I just noticed that the self-boot Ikaruga has 2 audio tracks before the data track - do I need to keep audio track 2 on the non-boot version?

Thanks Megalexxx.

[Megalexxx]

No you don't need to keep it. I don't think so.
But you need to have an ip.bin !
And binhack 1st_read.bin 0.
That's all, I think.
