Any idea which ic is used for the EPROMs?

That would be great! I'm always testing new test equipment and finding myself disappointed that I spent money on something so crappy. lol.

Yeah I got a few of them. My biggest problem with them is that some of the cheaper ones don't have any instructions and its a trial and error when testing. Some will say capacitor one way and then the other way they say diode. lol. I'm still learning and understand that I'll always be learning...

I thought so as well, it is just with the high rating he had, I would think he would want to know to avoid an issue. I know I would want to know if chips I got were bad if I were selling them. Definitely would help to avoid altercations down the road.

@stj @skate323k137 Chinese order of new m27c322 chips finally came in yesterday and they were the ones with the bigger window and they worked perfectly. Should I even bother sending a message to the guy I bought the other chips from to let him know they were faulty or just let it go? Thanks...

I also tried erasing and burning more of those "modern" m27c322 chips I got and they all still failed during the burning process. I then took the original capcom chip and erased it and try to burn it and just like the original 18 wheeler chip, it burned perfectly fine. So, the original rom chips...

Well... I downloaded the exact number that was on the chip... 23511c. I'd be happy to try someone else's 23511c as apparently the one I have isn't correct. :(

@skate323k137 @stj Well, now that the capcom eprom ic22 is burning correctly I'm getting further along. It at least goes as far as loading the capcom region screen then nothing. So, I did a game test rom board test and it is telling me that every single rom chip is bad, never seen every single...

Yeah I thought so, I've let some of the chips go for 30-40 even and they still say not blank and I'll have to run them through again and then they will register blank. Terrible.

Okay I’ll try it. It was a batch of 14 and I’ve gone through all of them and not a single one read even though they said successful and verified. At least not till I tried one of the originals. I’ll to clean the labels and see what happens.

@skate323k137 @stj Well, we have our answer... after I wiped the original 18 wheeler eprom and used it to try and burn a new capcom... it f*cking worked. I've literally been bashing my head in on this and it appears to be the chips the whole time despite them appearing to be the right ones...

Yeah, I wonder why they have the timer on the thing only go to like 6 minutes when it takes longer...?

I'll have to get one on order. Thanks!

Awesome. How long do you usually have to run it to erase an ic like the m27c322?
