I don't understand how it wouldn't be cost effective as it's still gonna use the exact same amount of chips no matter what and you don't need to to use tsop adapters if you stick to a 27c160 in 8bit mode. It would just be nice to not have to make a rats nest of wires and chips to get it done is all and I believe this project to be popular enough that it would justify making a pcb for it.

If you think it's cost effective, DO IT YOURSELF :lol:

P.S. we can talk about it from 30 buck shipped(per one) in a run of 50. Bare PCB :lol:[/quote]

I don't think it would be $30 a bare PCB. There are plenty of small fab company in China that do small runs for ALOT less
than that. I've had my hands on my pcbs from these places for the atari machines (2600, 7800 & 5200). Prices ranged from
around $1.25 to $5 a board pending the size of the board and how many are ordered. If you get a few hundred boards made
the price is pretty darn cheap if you plan on selling at least enough to cover the costs of the boards (not talking about the cash
value of the persons time to draw the pcb as thats a totally different monster). Hell I have got them by the box full in the past
with 9 boards per sheet. Silk screened logos the whole 9, but I just paid for them, I didn't do the gerber files as I'm not good
with gerber\egale\whatever software to draw the board and it's layers.

Thankyou very much for the menu. Let me start by saying I am very new to this. I applied the patch to Mega Man V (USA) version. I opened it with FCEUX and your menu appears. I then select "Rockman 5" from the menu and the game starts!

I'm not sure how to add the other games though. I see on your post you put.
"All games must be Mapper 4/MMC3 [D7--- ---D0] :
Rockman 5 --> 256 + 256 --> PRG + CHR --> XXX0 0000 --> 0000 0000 --> 00
Rockman 3 --> 256 + 256 --> PRG + CHR --> XXX0 0100 --> 0000 0100 --> 04
Rockman 1 --> 256 + 8 ----> PRG + SRAM -> XXX1 0010 --> 0001 0010 --> 12
Rockman 2 --> 256 + 8 ----> PRG + SRAM -> XXX1 0110 --> 0001 0110 --> 16
Rockman 4 --> 512 + 8 ----> PRG + SRAM -> XXX1 1X01 --> 0001 1001 --> 19
Rockman 6 --> 512 + 8 ----> PRG + SRAM -> XXX1 1X11 --> 0001 1111 --> 1F"

I attempt to add Rockman 3 to the end of Rockman 5 (I used the copy command on Windows. "copy /b MM5+mm3 MM16.nes" However this doesn't seem to work for me. Should this be all one rom that I can get to work on an emulator?

Thanks for your patience.


You have to use ReadNES3 to split the roms then use HxD to join the files :
PRG.bin Structure file :
Rockman 5 PRG
Rockman 3 PRG
Rockman 1 PRG
Rockman 2 PRG
Rockman 4 PRG
Rockman 6 PRG

CHR.bin Structure file :
Rockman 5 CHR
Rockman 3 CHR

Then you should program PRG.bin and CHR.bin to EPROMs...

If you are new to this, maybe you should start with a more simple project like this one :
Super Mario All-Stars NES Multicart Build

These Rockman/Megaman 6 in 1 carts are more prolific now and I decided to try one off of aliexpress.

specifically: http://www.aliexpress.com/item/Megaman- ... 44e59b955c

A couple of points worth noting here is that this does not function properly on clone hardware. I have a Tri Star Super 8 unit which piggy-backs off a SNES and a few games locked up and would not proceed: MM3, MM6

On original hardware there are no issues and everything works as specified. The issue comes up when speaking about the sound processing of MM1 & 2. Whether on clone or real hardware both games have distortion and thats why I am ultimately posting with respect to this.

Here is an example of the sound troubles on a similar bootleg (pardon the 50hz speed): https://youtu.be/523qkDi1Zyw?t=53 (also, check the video in the aliexpress link for samples)

I have no background as to the cause pardon searching and seeing the notes regarding the registers [#115318]. I also wondered if there was a conflict with the mappers and rom types not being implemented properly on cartridge.

All the same, there are cases where the sound is not distorted on MM multi-carts: https://youtu.be/NOJOX88UHTw?t=170

The issue isn't that the Rockman roms are different from the Megaman roms in the mapper department as I learned so I wondered exactly why this issue exists and what can possibly be done to remedy it. Here is further information as I found elsewhere on the exact circuit board in place on these bootlegs:
Quote:
Ok on the battery side the chip says:

HSRM20255LM10
F31M 271
Japan

The text in the upper left corner says "Pocket games" which seems to be the brand name of these boards.

As you can see there is what looks like a place to connect a chip as well as a few dip points. The one on the right hand side of the battery is closed. The one next to the chip looks like a solid blob in my cruddy pic, but it's actually 3, and the top two are closed together. It's labeled "j8".

---------------------------------------
The back of the pcb:

It says UNION at the top... it appears to be the pcb manufacturer. The serial on the upper right reads: SMD157D-72 (72 most likely stands for 72 pin as there is a famicom version of this cart). The large white text in the lower right says SMD151212.

On the top left hand side there are solder points for what looks like a diode, a dip and another diode respectively labeled D1 R1 and D2. Since it's labeled R1 maybe the dip is actually a spot for a resistor?

There is a blank spot for a chip on the left labeled U6 and a chip labeled U9 below it.

The large chip to the left is labeled U3 and reads:
MXIC 81325
29GL256EHMC-90Q
3P060800
TAIWAN

The square chip in the center is labeled U1 and reads:

SMD132
2015.11.18

The solder pads (for a dip) to the left of that chip are labeled 5/6K. The one below and to the right is labeled H/V (the rom order dip). The rest of the dip pads on this side of the pcb are unlabeled.

Were you ever able to solve this issue? I have this same multicart and I would like to get the sound working properly for mega man 1 and 2. If you are able to fix it, could you please share your patched rom so that I can have it burned to my cart?
