    SDLoader v0.12: run binaries from SD Card and backup/restore saves

    64 kB file for internal back up ram means that every other byte is useless and can be stripped out as the actual size of the backup ram is 32 kB. That should lower the transfer time.

    Graphics not fully loading on Sega Saturn

    @dblanchart Did you try to adjust the pot of the laser lens ?

    Graphics not fully loading on Sega Saturn

    Again, House of the dead streams those textures from the CD, and that corruption means they aren't read in time when the VDP needs them. And the OP console now stopped recognizing CD games at all. These are symptoms of failing laser lens or drive, with laser lens being the first thing to try to...

    Very unlikely that it would be a vdp issue, you would have much more graphical troubles.

    Graphics not fully loading on Sega Saturn

    I've had these kind of texture corruptions on ennemies in house of the dead due to a failing laser lens. The game streams them from the cd during gameplay. The music is also streamed simultaneously, which explains that both textures and music have issues in case the console has trouble reading...

    Action replay codes for nightmare difficulty in Saturn Doom

    Modified OP to add a patch to prevent the password being incompletely displayed if it contains the replaced letter. The nitty-gritty details of the patch of the password display routine : 060288D4 : 017C : mov.b @(r0, r7), r1 => 007C : mov.b @r7, r0 ; The password letter index can be loaded...

    Action replay codes for nightmare difficulty in Saturn Doom

    It doesn't appear to have been found already. There was a report recently on Kronos Discord by user WhiteySnakey that the nightmare difficulty could be unlocked in the PSX version of Doom, and he thought that since the Saturn version shares some similarities with the PSX one, that difficulty...

    Stellar Assault SS English localization project

    Great project ! AFAIK the interlaced mode doesn't improve resolution in that game. It sets the display in single-density interlace, and since the game runs at 30 fps, that means the same image is repeated on both fields of the same screen frame. So the effect is just to remove scanlines on a CRT.

    New dev on Saturn ... need help

    1. Mednafen is correct regarding 320*256 display. It is displayed correctly only on a 50 Hz console. It is shown as 320*224 on a 60 Hz console, the lower part of the 320*256 picture being truncated. The resolutions that Jo engine sets are hard-coded for each PAL/NTSC settings. There are other...

    New dev on Saturn ... need help

    Cycle pattern display was added in Kronos v2.3.1 in the General Info pane of VDP2 debug screen. Kronos 2.3.1 - 32/64 Bits : debug tools are back :)

    New dev on Saturn ... need help

    It was a cycle pattern issue. jo_set_displayed_screens calls slScrAutoDisp, which sets VDP2's cycle pattern register accordingly to the current settings of the layer that is to be displayed. In your example, if jo_set_displayed_screens is called without having changed anything to the settings...

    FBA WIP

    Only on the console, Atomic robo kid has cram dots crawling on screen. Does the game actually update color ram during display ? Also the timer on the continue screen is too fast, the full screen explosion effects are missing (when you lose your last life, or when a boss explodes), and the Atomic...

    FBA WIP

    The cue file lists a non existant wav file. Atomic robo kid still has graphics corruptions in act 5, less than before, so I was able to make it to act 6. Also at some point, when I got killed, I was sent back to act 2, and I had to get killed in that level to reappear in the last level I had...
