I have a followup to testing the starlight 64. I have good news and bad news.
The good news is that I did 2 99 stock tests in a row and it reached a maximum heat and it was only slightly warm. So it will not overheat.
Now for the bad news.
I had to remove the internal memory pak because it was unstable because the connector to the battery kept coming loose and wouldn't stay saved. You can still save with an external one though.
Also the low led did not work. But I'm not going to just leave a hole there. So now the red dot is just for show.
And now the worst one of the expansion pak chips has failed but I'm tired of working on it so it doesn't have an expansion pak anymore.
So now 3 setbacks have occurred but I don't plan to fix them. I have already declared the system finished so with those three things lost and testing complete it's now complete.
So it may go up for sale soon.
