Are you using any setting different from default ? If so, precise
Kronos: Core Options of Kronos itself are all at default. I tested with ST-V Favorite Region set to "US", but also tested the default setting of "EU" as well.
RetroArch: Some settings of Libretro/RetroArch itself are customized and I don't know what the defaults actually are and if any setting is relevant.
Did this game work previously ? Do you remember when ? Is it happening with other games ?
I'm new to Kronos and it's the first time I tried this game. As noted in the below description, Cotton 2 native Saturn version works normal and I can start game with Start button. Only the ST-V arcade based game from MAME ignores the Start button/key, but otherwise loads fine into title screen.
If applicable, provide error messages, logs, screenshots, or whatever additional information that could help debugging this
Kronos (core) installed and Cotton 2 game rom from MAME cotton2.zip loads fine, music plays, title screen shows up and I can insert coins. But the Start button does not work, even though its setup. Rom works fine in MAME, controller works fine with other cores and when I try Kronos with a different controller results in same issue. So it seems to be controller independent. Sidenote, the keyboard key for Start button does not work too, even if I explicitly set a specific key for it in the Controls menu of RetroArch.
I tried to load Cotton 2 (Japan).chd as a native Saturn game in Kronos; and it works fine with Start button and I can play the game. Just the ST-V arcade game does not work (at least the Start button).
I found this closed issue for Yabause (which Kronos is based on) without much information or resolution that might be relevant: https://github.com/libretro/yabause/issues/300 1 Other users from RetroArch forum reported same issue of Start button not reacting in Kronos core as well.
I’m on a Linux system. RetroArch 1.18 and all files updated, core Kronos just installed and Bios files present.
If I run Kronos with “ST-V Service/Test Buttons” enabled and go into the test menu to check the input device, then the Start button is recognized even with the ST-V game is loaded in. It's recognized in the input test menu, not in the actual game.
Log generated with retroarch --verbose 2> retroarch.log in the terminal attached as a text file.
Also seeing this with Cotton Boomerang. The start button tests fine in the ST-V test menu. The test/service buttons do not work in the Cotton test menu.
