Sega MegaDrive/Genesis Test ROM?

Hi Guys,

Hope everyone is well. Have a few sick JPN Sega Mega Drive model 1's, and was wondering does anyone have a ROM of a test much like the SNES burn in test cartridge?

Thanks

 

I would like that.

 

Are you talking about something like the 240p Test Suite?

 

Thanks for the replies. Can see the 240p test, however im more after a test suite to test cpu ram etc on the md/gen.

Problem im having with this jpn md model 1 is graphics artifacts and white dot patterns.

I have removed the cpu, wram, video encoder, video ram and installed sockets. Have removed the same components from another md and also installed sockets. Have replaced the two 7805's and installed a new DIN.

Also this md is an asian pal md, so it had that dodgie 50hz colour correction they did in the day.

Have not done caps yet, might do that next as it gives me a vaild excuse to use my desoldering gun.

Thought a test suite would help alot in diagnosing issues and save time.

 

Sounds like you need this:

Currently out of stock, but I imagine they'll get some more in soon.

 

Could just download the rom here:

And make your own cart.

 

Do you think I could use this to diagnose my TH (select) signal not coming from the I/O chip?

 

Awesome. Thanks for the replies and link.

Sorry freezerburn im not sure.

I plan on putting on an everdrive and trying later this week
