Arcade Rom Patcher (V15)

[Hitesh]

Just been going through this thread. Thanks for this. Its amazing.

I had assumed this was only for physical roms and PCBs and would not work on MAME but gave it a got yesterday patching AMIDAR and HUNCHBAK.
Both worked but the HISTORY.DAT for the LUA PLUGIN does not have the correct infor to save the INITIALS/NAMES.
By using LOAD/SAVE STATES on Mame, I have managed to get nearly there but can HISTORY.DAT be modified?

The relevant lines are :

amidar:
amidar1:
amidarb:
amidaro:
amidaru:
@:maincpu,program,8200,1e,00,01
@:maincpu,program,80a8,03,00,01


hunchbak:
hunchbaka:
@:maincpu,program,1c07,68,00,00
@:maincpu,program,1c34,1,20,20

Regards, Hitesh

(I have on my front end a "Guest High Scores" menu and its great to see visitors try to get on high score tables. I only have games there that can save names. So that menu has no Amidar, No Hunchback, No Space Invaders......)

Just checking in since I have a new PC and I'm reinstalling. Is V14 the latest and greatest? Or did I miss where they are being posted on Github or similar?

Thanks in advance!

Yes it is. I haven't had any time for patches recently, though I have just corrected the R-Type I patches as there was a problem with the spaceship being corrupted once you shot it up. Only took 6 years for someone to find the problem.

I just scored two Pound for Pounds earlier this month that I haven't had time to convert, so I'm looking forward to this. Thanks again for all your hard work. Arcade Rom Patcher is amazing.

Maybe a question asked before:

Would freeplay for the Namco System 1 games be possible, too? Galaga 88, Pacmania, ....
Very selfish question, but I added a few more games to my lineup...

Although v14 has been out for a while, I just noticed it had a gfx fix for popeye bootleg. Have 2 of them both with the same (know) issue (that has annoyed me), so exited I patched the roms and installed them. Unfortunately it still has the color issue, is this something that can be patched?
Another question, I have several wonderboy bootlegs, some have the 305-5025 chips and some have a daughterboard to replace them. The ones with the daughterboard have a glitch that creates small lines on the top of the screen when the screen is scrolling.
I this something that can be fixed with a patch or is it as I suspect a hardware thing?

There was a post on here recently about the sega 5025 custom chips and a picture of a bootleg using 74HCT356 as a replacement. Maybe it's possible to swap them for 74HCT356s instead of the daughterboards to fix the line issue?

Nice fix on the Popeye title screen I remember myself and @Purity trying to find a solution to that issue years ago.

Found the post, and asked how this works. Doesn’t seem possible but who knows. Regarding the popeye yes graphics are fixed but there’s still the issue with the colors around the eye.

The colour issue was on my bootleg as well. It's caused because the display is part tiles & part sprites.
It seems that a bunch of these bootlegs were put together badly. There is a block of resistors next to the right corner of the edge connector that are incorrect, I can't remember if the silkscreen is correct and just the wrong values were put in or wrong silkscreen & values.
But the circuit basically has 2 sets of resistors for the RGB, one for tiles & one for sprites. If I get a chance I will dig my board out and report back. Even with the resistor changes there is still a slight difference but it is much better.

Forgot to answer this one!
There shouldn't be an issue from the replacement chips, in fact the Midway 6 pack board had the layout the same as the bootlegs for when those chips weren't available.
I think the problem is probably related to the interrupt routine which is take too long so the board starts rendering the display while still updating registers. If these are the glitches I think they are, then they also occur on some original boards. I hit the problem when developing my multi and for an original board I found that disconnecting the M1 line from the clock divider worked. I think it was there for the protected CPU's so that they had a slight delay for the encryption lookup delays.

Yes the ’glitch’ I meant are the vertical lines that are in the top score part of the screen. When you walk the background scrolls, and every 8 pixels of scroll (or something like that) the lines appear and the when moving another pixel they are gone again. I had 2 of these bootlegs that are exactly the same but instead of the daugterboard they had copies of the 5025‘s and they don’t have the issue.

Did you ever do a 'De Protect' for the King Of Dragons CPS1 ??

It wasn't a game I was interested in at the time so I didn't do it. I still have my notes and source code but it would take some time for me to get back in the CPS1 zone and at the moment I am quite tied up with family stuff so it won't happen in the near future I'm afraid.

No problems mate , Hope all goes as well as it can with the family stuff mate. I can program a 21 to be an 18 so should be ok.

hello,
im wondering if someone has the 3 colour proms to Gal files for wonderboy in monsterland.
(pr11026.20, pr11025.14, pr11024.8).

what gal chip would work instead of this proms?
dave

 

[TheDaddy]

Ah maybe not. I found the Gal files then reread you question.

Maybe better to post in ' Tech Maintenance and repair '

I am not sure you can sub GAL for prom?
Usually people are asking for PAL to GAL conversion.
Is there a reason you cant use Prom files and get replacement proms burned instead?

i dont have proms - i have only gals

where are you located? They are small and easy to ship. Someone can get some burned and sent to you for sure.
hobbyroms.com is first stop.
