It now more than year after article were released but people stil asking me again and againd about this stuff, people still belive that flashcarts can burn their consoles. I seriously tired justify oneself, so i decide to make this topic and then just point here all who ask about this article.
First of all i would say that almost all modern everdrives used voltage trnslators from 5v to 3.3v bus, the only carts which still use direct connection between 5v and 3.3v is mega-x7(partially), everdrive-gg and flaskit. So, modern everdrives does not have have any risks, even if db-electronics would right.
Now i would like to say few words about Rene's article: It based on incorrect data and it makes most of his statments is false.

1. Rene used in his calculations 4 times less ratings than they actually are. He says: Typical CMOS ratings are ± 5.2mA. According to his own calculations IO loads on old everdrives around 7mA. But JEDEC specification cleary says that IO current limit for CMOS devices is 20mA and not 5.2, as Rene says. So, actually we do not out of specs, it means that whole article on Rene's blog lost the sense. When i point Rene on this facts, he just say nothing in reply.

2. Altera designed IO clamp diodes on some of their devices for interfacing with old 5V PCI bus, so according to Rene Altera's enginers an idiots who designed feature which burn motherboard chipset, right? For devices in industrial scale,  which sold in millions units it means huge amount of  burned systems. But Rene probably knows something special what does not know anybody else

3. And now is example of outright lie from Rene: He claim that some everdrive does not have ground pour, and as exemple he shows mega-x5, but mega-x5 actually has solid pour on back side, and most of recent everdrives use 4-layers pcb with dedicated layers for power and ground. But when i pointed Rene on this facts, he just ignored me, he did not fixed his article, he knows that it is not true but leave all as is.

This all make me think that it was done deliberately, may be for hype, may be he is kind of everdrive hater, i don't know...

Also i suggest to look this small video with alternate vision: https://www.youtube.com/watch?v=vv4TeyLcSSw&t=12s

Mega-X5 which actually has ground plane:






Rene Ignores my argument, he say nothing in response

News / MEGAOS-V3.05-RC2 (test build)
« on: November 05, 2017, 02:09 AM »
Here is new MEGA-OS build for testing. This update has lot of changes and here is the list:
MEGAOS-V3.05-RC2
1)Fixed YM2413. Latest update from Necronomfive
2)Changed controllers detection code
3)Fixed possible micro freeze when exit from Options menu.
4)File sorting option. Folders with more than 256 files will not be sorted
5)New ToolBox menu. Contains "Game RAM to SD", "SD to Game RAM" and "Reset to Default" functions. Alos some functions were moved from main menu to ToolBox
6)"Game RAM to SD" and "SD to Game RAM" functions allows to copy current SRAM content to/from SD card. OS runs this functions automaticaly every time when user select new game, but now they availalbe for manual control also. For example, you can run "Game RAM to SD" manually if you afraid that battery will dry and you will lost progress from last selected game. This functions is inactive on mega-ed-x3, because this cart does not have battery ram.
7)"Reset to Default" allow to drop all settings to factory defaults
8 ) Improved cheats interface. Now you can set cheats settings right from file menu, even without game selection. Also system will remember on/off state for each code and will not turn on them all every time when user select the game. Cheats interface is bit more handy now.
(!)This OS version will resets setting to default, so, backup your saves from last played game before update

EverDrive N8 / Warning! Another cheating from Clone sellers
« on: October 28, 2016, 06:26 PM »
Recently i disovered that some sellers offers N8 clones with OS13 preinstalled. I bought one to check what is going one. And what i see, they just mixed menu ROM file from OS v13 and mapper files from OS 9. Seems like this is next level of their impudence  ;) So, now menu shows V13, but by the fact this is just an buggy monster with functionality which stuck on the level of OS v9, but additionally now this have some extra problem due the mixing of files from different versions of OS.
