Thanks in advance

 

Bipolar prom, use a decent programmer to read it.

 

Do you have this decent programmer? If yes PM me please.

FTDI can't read the prom?

Is it possible to buy one Bipolar prom dumper? at what price.

Hello,

I need some help with this Poker game on MAME.

I dump all ROM including bipolar ROM (with the help of Bad_Ad84).

I need to CLOSE THE DOOR in game because the DOOR IS always OPEN.

Look this picture:



Who can help me please?

Perhaps I need to change Hex in ROM file?

Thanks in advance

Here are the roms for the poker game:



Here is MAME32plus (last release) with POKER ROM (pepp0065):





WHen I start the game for the first time I have this error:




A doc : http://www.gamesdbase.com/mame-rom/pepp0065.aspx

 

Any dipswitch settings in MAME you can play with?

 

I have downloaded Mame32_Plus!_V0.147_win.zip
If you can search for me please? I don't find dip. set.





Anyone want to help me please?

I want to close the door.

My poker game had been dumped by me.
It's not the pepp0065 roms finded on internet.
It's not the same game but it work on a machine with door closed.

 

I and O are obvious keys to try pressing.

 

One important thing to know:

The original pepp0065 rom file is not the same as me.
I have a motherboard. I have dumped all roms and rename them to work with MAME.
My ROM doesn't exist on Internet.
Is it possible to close the door?

nb. I and O doesn't close the door.

 

Are you familiar with the term "Trainers" and "Cheatcodes" ? not that im trying to "teach" you something, but these terms can make you search for Hexvalues inside a running mame session, and when the message apears you like to change to can try lookup witch function is making it display, changing its state before the value is read maybe changes the state of the door inside Mame. (I hope it makes some sense)

 

Cheatcodes I know on Zsnes or Snes9x but not on MAME.
I send you a PM.
How can I do? explain me step by step please.

@CodeASM:

Can you help me if i send you the ROM please?

 

Ive got the roms working to a same state as Trevormacro and Im gonna try using a debuuger to identify where the code is checking the door.
http://www.jeffsromhack.com/toolbox/mamedebug.htm is a good one I hope

Im no Arcade owner, never touched the internals of one, but as an Programmer I might find an answer. the C file used in Mame apparently knows where the buttons are and its statuses, maybe that will be handy to change or add a new version to



Oke, i think recompiling mame is the way to go.
What the thing is, is this:
Original in the specific C file:

So as you can see, its comparing the CRC and/or SHA1. It errors, because our files are diferent, not much do. So You can run it anyway.
But as far as I understand, the rom image is mapped using pointers into the MAME system.
And Here is where I think our problem is. maybe not, but im gonna add a new game anyway.
because the ROMS I got from TrevorMacro are diferent in size (not all) and ofcoarse the CRC.

his pp0065.u68 (he named it so it will work sort of) has an size of 32.768 Kb and CRC of 3F5D8A67

This is not equal to 65.536 of the original, with CRC 76C1A367

The original one is packet a lott smaller, so maybe we missing some white space. Actualy I need to ask if its posible to make another dump and compare (Unless that is already done and we are sure the dump is 100% to its eprom)
Anyway, I dont know for sure but maybe we need to give it an new name/number?

I keep you al updated

 

@CodeAsm:

I redump the pp0065.u68 chip and it has the same size 32.768 Kb with CRC of 3F5D8A67.

 

can you try the cap740.u50 ? cecause its size is larger than 512.
I asume it is correct, so If im changing the C file this week (Maybe tomorrow) it may work better.

I was cleaning my room today and doing laundry, no time for other things. found something(for the PSIO project)

 

Bad_Ad84 had dumped my cap740.u50 correctly.
It's only for color management.

Hello,

Any news at all?

 

I was very busy with other things,
But ill take a look in a minute, at the airport now (dropped my gf at the train to see her next saterday again.)

EDIT: compiled normal Mame, took a while. Now looking into making some changes, the pepp0065 config seems to have a Door value, but its value is set to 0, changing its default value or normal doesn't seem to impact its behavior. my compiled version is likely the same as the downloadeble version, no use, just a test if my setup was able to compile.
image of your rom into my compiled Normal version.

 

Ok,
When did you continue?
Is there a solution to close the door and play game (insert credits)?

Thanks

 

done some last night (19 hours ago?) and just some this morning and now. (its 18:48)

I have problems running a custom pepp0066 version, tried adding 0066 based on 05 and new crc, only need to calculate sha1 to be correct. I dunno why its failing, compileing takes forever. I try again in an hour (Did some testing at work, they kinda where intrested, was afraid of problems XD )

Anyway, no luck yet, but maybe some adress problem or memory problems. or autohold, will try the last first. just close door and we are happy.

 

I hope it will be good.

If anybody want to help me?

 

Wo speed up the compile process, use a -j switch, -j5 uses more cores I hope the right one for my cpu.
Anyway, I compiled Mame with debug on and directly saw just a small error again, but the game runs.
Again with the door problem. Error log is saying the game "Umapped i/o memory write to 0A044 = 00 & FF" and Many many more adresses.

Image is with debugging on and game is running my modified pepp0056 (new crc and sha1, memory larger or smaller acording to filesize (bug, as seen on image))

 

game run and the door is still open?

 

yeah, door still open. with my newest edit the game nolonger runs... cpu is not gettings any codes, so I need to edit some stuff again, still in progress. will post some code later, so others can try/see/help.
