Issue with new Everdrive
« on: June 10, 2019, 04:23 AM »

We picked up an issue with the 4MB Everdrive. Discussion can be found at the end of this thread at SMS Power

Past the first 1MB everything appears to be mirrored. My guess would be you have some legacy code applying & $3F to bank numbers before use. If you have any questions send Calindro or myself a message.

I check game mapper code and i found that it really does not decode address over 1M in game mode. It not affect commercial games, but large hombrew and demos will not work. I understand that it could be important for some people and i ready to replace such carts. Just put your requests here:

Would be cool if you repost this message on smspower, i can't post anything myself due their aggressive antispam policy (:

Thank you for the information. I have posted your response on SMSPower....although I could not provide the direct link there to this thread because of their policy to newly registered users. I have emailed you as well through the contact form for assistance with my Everdrive as well. Thank you!

Edit: It appears I cannot run the Bad Apple demo as it requires a PAL region machine and I am NTSC. But, I think even for PAL region they may have a problem running 4MB demo. I have sent you some pictures of test results. If anything maybe this can help people in the PAL regions run larger homebrew. I wish I could run it :(
