EverDrive N8 / Re: EDN8 Boot Failure
« on: November 21, 2020, 11:27 AM »
OG N8 update problems usually related to mapper files fragmentation on sd card, especially if non windows machine was used for setup. Cart support rom files fragmentation but not mapper files fragmentation. Boot problem can not be related to OS bug or something, if previous version works fine before, because i literally just changed version number and modified fds mapper, nothing else was changed. Any parts of update is not stay installed inside of cart, everything on SD card.
Blue screen means that bootloader can not configure fpga, there can be two reasons: 1. file 255.RBF fragmentated, 2. cart is broken. Second option can be easily checked by booting cart without sd card, if it shown typical error message about sd init then fpga is ok

Are you sure that you played exact same rom on x7? I tried on x7 13mb rom with bonus tracks and it fades to black after Williams logo just like on PRO. Roms over 10mb actually shouldn't work on real hardware, because area over 10mb occupied by the system registers. Such big roms can be played only if they be designed with using SSF mapper, but they don't.

regular N8, not PRO?
Try diagnostics menu: turn on cart without sd card, then when error screen pops up insert sd card and push select+start+a+b

Could you show the photo of cartridge pcb?

Unfortunately I don't have any ideas what it could be. –°onsidering there is no mass reports about this problem i assume that problem related to your certain setup. Usually i can't provide solution if i can't reproduce the problem myself. May be if you can describe some details which could help to reproduce the problem then i will find solution.

N8 clone? They usually has such symptoms

He-he, modern flash carts is a good health test for your console (: Fortunately those graphical glitches is very specific and clearly points to the possible source of problem, usually pretty hard to say something without full diagnostics.

9
Likely something wrong with /AS (B18) signal on your system (or on cart). Check if there is no some visible defects on that pin at console and cart side.

Please check if Virtua Racing has mass glitches also. It looks like one of control signals does not pass from genesis to the cartridge.

Free Run does not work with MegaSG using x7 or PRO, problem source unknown so far. But working fine on original systems. One of customers said that Free run works fine on MegaSG with older firmware.
Thanks KRIKzz. How can I help you track this down? I have MED Pro and Mega SG. Note that it does work fine on Mega SD so I think it is fixable via MED Pro firmware update

It fixable for sure but so far i have no ideas how to track it down, i tried but without success. May be it even not directly related to SVP core itself, for example while ago i fixed bug related to soft reset cmd which rarely used by games, only few known games uses it at startup. On MegaSG with Mega-pro those games just hangs, but worked fine with MegaSD. After all i found that MegaSG core has a bug which causes this problem: after soft reset cmd MegaSG begins fetching data from cart before than reset signal actually was released, but cart isn't response because reset still asserted by the console. At same time this behavior does not have any effect for MegaSD, likely because MegaSD does not return to menu after reset and reset signal not affect the cart whatever happens wit it. I was able to fix this problem on my side but this case explains why sometimes hard to have deals with clones, original systems also may have some bugs but they documented at least, but in case of clones usually no any info.

While I was writing this message, I got an idea that i should check if described above behavior isn't affect VR also. Hm...

And yes, message didn't show up again afterwards.

That's normal.
