I will detail a series of problems that I noticed for those who are like me last night (cursing the universe itself XD),the psx console works correctly as long as the bios are not placed, but once put we will notice that neither psx nor Dreamcast nor PS2 will work correctly,the problem is with the psx files found in the BIOS, the only way to make it work partially well is to delete them, once deleted the games will work some well others more or less and others will not work, The files that psx recognizes are: bin, cue, zip and chd, With games like Diablo of the problems that happened was that the game starts once and works fine, but once we close it and run it again, the screen goes black, does not load or Nor does it return to the main menu, other consoles such as C64 (Comodore 64) also present similar instability although less but the good thing is that the bios update does not affect it, There is also the connection to the internet via wifi which is null, even if we put the name of the network manually, the only way is by cable, but forget it wireless. In summary, in the case of the 32-bit version, my analysis is that it is still a bit green, I would recommend installing the previous version (5.25), I have been testing it and it works better, the update The bios does not affect any console, it has other problems but they are not very serious things, the only problem is to get the version and get the bios, the bios is more available, but 5.25 For some reason it was removed from the batocera page, so in order not to make them curse the universe as it happened to me, I leave here below the links of all the versions prior to 5.26 Along with the BIOS.
