So, aberu is there a hex editor that you recommend? I use HxD --> https://mh-nexus.de/en/hxd/ - just because it's what I'm used to. I'm sure there are better ones out there that people use. Hex is hex though, not much for a hex editor to do in general :P. Looking around, this looks cool, I might try it out --> https://github.com/WerWolv/ImHex and ...

You could go to this hex offset in a hex editor for the ROM to find out specifically what the region is. The regions are not typically "U/E/J" for Sega Master System games. There is no real way to tell that "it should run at 50hz" without real hardware from what I can tell. And even then, this would only apply to games that wer...

Setting the console to Japanese region can be interesting. The Mark III doesn’t have a BIOS, so games will have their own sega logo screen which can change between games like on mega drive. There can also be changes in the game itself - wonder boy in monster land’s bosses have doubled HP compared to running the system in US/EU mode for example. Pl...

For games of this era, it was standard practice to simply let games run slower on 50 Hz systems rather than try to alter the behavior. A game running slower on a 50 Hz system may be "correct" behavior in that sense. Ideally, anything with a J or U in the region code should run correctly on a 60 Hz system and anything with an E in the reg...

So, was curious if there is a easy way to tell if a rom uses a specific region US/UE or Japan. And also whether or not it is a NTSC or PAL. I know that in the US and Japan, NTSC is used and Europe uses PAL. However, my question is related to roms specifically. Trying to understand how to figure out if a rom is playing to slow or to fast, etc. Becau...

check the header in Mesen or other ines header software and change to the correct mapper. If the mapper is not supported, you can always request it here: https://misterfpga.org/viewtopic.php?f=17&t=5 To change the actual mapper of a NES game, you'll need some serious 6502 assembler knowledge I will work on it, and see what i find out. Thank yo...

Check out the MiSTer NES core page for supported mappers: https://github.com/MiSTer-devel/NES_MiSTer Use this page to see what games have what mapper: https://nesdir.github.io/ after putting them through the script. and still find out they don't work, how do I find out if the rom has the wrong mapper? and then how do i change a mapper if the rom h...

JWDog

Ok. Cool. Thanks for all of your help.

Is Mesen a good emulator to look at the header of a rom?
Do you know if there is a list out there of .nes roms that don't work with MiSTer?

JWDog

So, I got the script to run... But, now I am noticing that it didn't look at all the .nes files.

Is there still a problem?

or is it limited to how many .nes files?

JWDog

I suspect you have not grabbed the python script correctly. It's probably the correct script but wrapped up in a HTML page. How did you download it? You're probably right. I went to the github page and right clicked on the name of the file and saved it. I didn't see a download for it. Ok. So, I went back went to the code and downloaded the zip fil...

I think it actually does. What does that mean? Do I have the wrong .py script?

JWDog

If I use Mesen emulator to check the headers, do you think I could discover more info?

JWDog

How do i change the .py script code to what you suggest?

JWDog

if the .nes file looks like garbled data then it could very well be a rom, try it i an emulator maybe to see if it works there? It is a rom. Maybe i dont undetstand this header business. But, i tried the rom in MiSTer and it didn't work. So, thought i would try this method. And still having trouble. Most of the roms i have work in MiSTer with a sm...

JWDog

Just open the file in a text editor and search. iNES header entries looks like this: <game> <prgrom size="16384" crc32="D3D248C9" sha1="64185EDC4FD64B5F5E565B90B0DDC241592D899C" sum16="0339" /> <chrrom size="8192" crc32="9C124A53" sha1="...

So, i tried it again adding more .nes roms and get the same error. Not sure what is happening... here is the cmd.exe statement again.

JWDog

I understand. Maybe i should try more roms that aren't working except just 1. To see if the script is really working. I will try that and post the results. Does anyone know if there is a list out there that shows .nes roms that are not working on the MiSTer?

JWDog

Thanks. It is strange because the rom in the folder is .nes. do you think it could have problems if the rom is a japanese famicom rom?

JWDog

Use kitrinx NES header repair https://github.com/Kitrinx/NES_Header_Repair with the INES header db http://forums.nesdev.com/viewtopic.php?f=3&t=19940&p=248905&hilit=Ines+2+script#p248905 to make your nes headers up to date I have the nes20db.xml and nes_header_repair.py, and a rom in a subfolder So, I am new at this and tried to run th...

JWDog

Thank you jca! Your help has been much appreciated. I will post some results incase others have issues.

JWDog

It is visible in MISTer when I back out of the directories to the root of the hdd. I don't have a problem with needing the file, just want to hide it so I don't see it in MISTer.

JWDog

so the problem isn't that it is too big

though i will have to check if it spinsdown... then I will have to use the script.

JWDog

jca: I got it to work. I must have had to reattach the hdd to my PC and it had to repair it, must have not ejected properly or something. then got it to mount as you said. Thank you so much!!! now another question... how do i hide the recycle.bin directory that windows makes?

JWDog

Thank you i will give it a try and let you know what happens. thank you for all your help! awesome!

JWDog

it also states that the operation is not permitted.

JWDog

it says the following:

The disk contains an unclean file system (0,0), Metadata kept in Windows cache, refused to mount.
The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume as read-only with the "ro" mount option.

JWDog

i typed mount, but "/dev/sda1 on /media/usb0 blah blah blah" did not show up. This is what i got.

JWDog

the results of the blkid

JWDog

looks like it is seeing it right?

JWDog

Here are the results of the fdisk -l
