Gunnail Low Health warning sound

[Battlesmurf]

This is probably on the sillier side of things. Gunnail has a low health sound, but also a reason (scoring) to be on the lower health side of things. Is there a way to remove this and get a custom rom set burned for a PCB? Any pointers on where to start the search?

Thanks!

[trap15]

I was probably going to do this soon. I'll post back in here when I finish it, it shouldn't be too hard to do.

[blackoak]

haha, i've been eagerly awaiting this too.

[Battlesmurf]

Superhero, many thanks! I'm poking around your website now- if memory serves you had a few arrange sets done already? I'd donate to the Gunnail cause.

If anyone in this thread owns a Gunnail PCB with a single program EPROM instead of two it needs to be dumped.



No desoldering, the job is done in < 2 minutes. If you want to contribute, PM me and I'll hook you up with one of our brilliant US or EUR dumpers.

Ask yourself, what have you done for emulation lately ?

[Battlesmurf]

I'm curious to learn more about that single Gunnail. NMK stuff makes me happy lol

[Ed Oscuro]

Oh, I'd love this to get fixed. Silly NMK, adding shit to your games

A brazen trick to get me riding the edge of needing another credit for the whole game - OK
A little noise - NOT OK

[SuperDeadite]

Honestly the noise doesn't bother me, but as a PCB owner I'm quite used to it. I just hear it as if I'm in a hospital. that beep is my heart beating, the beep let's me know I'm still alive, riding the very edge of the knife. When the beep stops, so do I.

[system11]

I'd run an alarmless version in preference.

I think superdeadite has this board, check this video: https://www.youtube.com/watch?v=tf15Wz0zUiA

Would it be possible for you to get your ROM dumped SuperDeadite ?

[SuperDeadite]

Not opposed to it, but I'd rather not ship it overseas. (I'm in Japan)

Brilliant, no worries we have dumpers in Japan

Here's a quick single-byte patch for you folks at home.

Open a dump of the '2' ROM (92077_2.bin in the MAME set), and go to 0x52E6.

Change it from 0x9D to any value between 0xFD and 0x8D, only changing the top 4 bits. 0xFD is quietest, 0x8D is loudest. I find 0xCD to be particularly nice. 0xFD is practically inaudible. Remove bit 7 (0x8D turns to 0x0D) to prevent it from overriding the last effect in the same channel.

Easy mode: Just replace that byte with 0xCD.

[blackoak]

thanks! i'll try it out this weekend.

the legend of trap15 continues...

[dink]

Very, very awesome! I'll be adding a special dip-setting to fbalpha for this with regards to trap15

Got it. Anybody have any (possibly PM) suggestions on a way to test run this before I burn it and put it on a board? Shmupmame gives me a CRC error that I can't seem to disable at the moment. Open to alternatives. Thanks

[dink]

Battlesmurf, MAMEUIFX will play the modded rom without issue, also make sure the new crc32 is C6623BF8 if you changed the 0x9D to 0xCD and you should be all set to burn it.

[Battlesmurf]

Dink- you are a superhero. Test burn works great.

Loosely related- has anybody had success with the roms for SameSameSame (preferably with actual hardware?). I haven't had much luck patching that one o.o

[cave hermit]

For the record, most versions of mame will run modified roms if you:

-Run from command line (open command prompt, navigate to the mame directory, then type in "*name of mame executable here* *name of zipped rom here*")

-Use a batch file (just write "*name of mame executable here* *name of zipped rom here*" in a text file, and save it as .bat in the mame directory)

-Use a frontend program

I can confirm that they work on real hardware. Great changes too, it makes the game feel a lot less punitive.
