Re: moonwalker system 18 sega problem

My suggestion is, considering that it boots, go into the service menu and run the memory test option.

Re: moonwalker system 18 sega problem

I think one with a dead encryption processor doesn't even give out any video?

Re: leonardoliveira & Idc's clean decrypted roms

I suggest you try moving your 03-06 EPROMs into another CPS2 game (that is battery less) and see if it boots up. Even with screwed graphics and sound you can at least see if the programmed EPROMs are working properly...

Re: leonardoliveira & Idc's clean decrypted roms

Please look the zip file, inside if the date of the file 03 is from yesterday. I tested the file which were at the site, which indeed failed as you described. I patched, updated the file 03 from the zipfile and uploaded again. All six versions of "Ultimate Ecology/Eco Fighters. I know it is wor...

Re: leonardoliveira & Idc's clean decrypted roms

Oh thanks :awe: Will download it this evening, make a test run and update this thread here. Hopefully everything works fine. If you look around the site you will notice that I updated all versions of Ultimate ecology, including the non Japanese ones. The problem was that I re-ripped all of them usi...

Re: leonardoliveira & Idc's clean decrypted roms

I just went to the avalaunch site, downloaded the file uecologydl.zip from there, compared against the uecology set used with Darksoft's CPS2 multi and it's exactly the same data. Indeed, the file has problems but here's the fix: At position 0x1F4A change value 0xFF for 0xBF. That will prevent a mem...

Re: leonardoliveira & Idc's clean decrypted roms

You have to reprogram all four chips at same time using the four files from the archive. Unlike other games which have just chip 03 or 03 and 04 encrypted, this one has the whole program encrypted.

Re: leonardoliveira & Idc's clean decrypted roms

No, version (date that appears on power on) of the GAME, not the board code. :)

What is written on the stickers could also be of help. This game is one of the cases that ALL EPROMS change between revisions.

Re: SSV 3.6v nicd questions

Finally got home. The plus line from the nicad, and if i am not mistaken, goes to R3>D3>D2>D1 and from there it goes straight into leg1 of the sharp LH5168D. Charging circuit into buffer ram? I am not good with these things. DSC_0231.JPG It's likely this: D1 connects the + side of the Battery to th...

I tried to get my dead Ultimate Ecology fixed, but with the ROMs from the site it won't work :(


Which revision is your board ROMs?

Re: NAOMI 2 fans

The 12v fans are cheaper exactly because PCs use them (sell a lot). Unfortunately the GPU fans seem to have speed monitoring in them.

You may safely ignore the sensor pin on the 3 pin fan for the casing.

Re: NAOMI 2 fans

The third wire is used on PCs as a monitoring signal so the computer can tell how fast the fan is spinning (or if it is stuck not spinning).

The PC fans are 12v. Make sure you read the sticker on the naomi fans to check if they're 5v or 12v fans.

Re: Motherboard cps2 no sound on output RCA White Left

The chipset (two Toshiba chips) that controls the volume on the CPS2 are designed for automotive radios so it has more functions than just volume control. It has some RAM powered by a super capacitor which keeps the settings. If it goes corrupt you may have, for example BALANCE set all to right or l...

Re: SSV 3.6v nicd questions

Ok lol then in that case its safe to assume you could replace the battery with a battery holder and rechargable coin cell. Unless you disable the charge circuit. Yes I think that's the reasonable way of dealing with that problem. I Suggest you fit some long wires and use the exact same kind of batt...

That M6295 IC looks pretty ugly to me (soldering). Maybe that one is the sound issue?

Re: moonwalker system 18 sega problem

On most computers here's a circuit with a capacitor where the charging of the capacitor controls how long the system master reset control line is held down during the power up. That behavior prevents that some parts of the system start up earlier than the CPU is able to take control of the system, k...
