    I'm not aware of an Rmenu.ini at all, at least i don't have one on my card. Just drop all the Rmenu files into the "01" folder, run the exe and follow the prompts.
    It will automatically build the .iso with the list embedded, you just have to do this again every time you add/remove games on the card.

    Thanks for your answer, i have no idea what was the Rmenu.ini around hehe.

    Other short question, is there a compatibility list for games? Im pretty happy with my RHEA, finally everything setups even the List.ini for the Rmenu, but for some reason some games has Graphic errors, like AMOK or Earthworm Jim 2 (which even stop loading in the PAL version, US has graphic bugs). For AMOK when i put it only on a 8gb Sandisk card it works fine, when i put it on my 128gb Kingston i have this errors.
    I also tried to convert in an other format then CloneCCD, but without success.

    Does anybody has an simular problem?

    Thanks in advance.

    Not on my end. Make sure your sdcard is formatted with the correct cluster size, your games are pure rips and if I recall correctly while other iso types are supported .cdi is most compatible. As for the pal games you might need to solder a wire to the 50/60hz pin on the saturn. Maybe not.

    Rhea has a spot to solder to that lets it auto switch so that could help? I haven't gotten to it on my console yet.

    Thanks for your answers, i will check when im back from work :)
    The problem with CDi its difficult to get, i buyed UltraISO already years ago, it support alot of formats, but CDi :( Thats the reason why i used only .iso .ccd .mfd. Currently this are the only 2 games which was difficult to handle, even NTSC-JP games works fine (tried Dracula X)

    I'm sorry I haven't posted anything about the menu in here for a very long time, but a while back I actually did a bit of work on it and even made a beta version for a few people to test out.
    At the time I had planed to add a few more features and release it around early December or so, but unfortunately that never happened...
    So since it's fully functional I decided to just release it as-is anyway (should've done this sooner), plus a bigger pool of testers wouldn't hurt just to confirm that the patches work on all bios.
    Hopefully sometime soon, I'll find the time and motivation to work on it again and implement the things I had planed ;)

    List of relevant changes:
    - Implemented in-game reset patch (fast boot only), triggered by pressing A+B+C+Start or the reset button
    - Added selection menu to choose the boot mode (fast boot, full boot and load cartridge)
    - Improved the loader compatibility
    - Game titles are now ordered alphabetically in the menu and no longer forced to all uppercase
    - Minor changes to the GUI

    A screenshot to show the slight changes:

    Download link in case anyone wants to get it a try:
    http://www.mediafire.com/file/tdkdyqbtjdf44k3/RMENU_v0.2_beta.zip

    There's no readme included (who reads that anyway) but I think most of the changes are self explanatory.
    Probably the most important addition is the in-game reset, and in order to use it just make sure you add the line "reset_goto = 1" to your Rhea.ini/Phoebe.ini file.
    As mentioned above it works only with fast boot since there's some tricky patching involved, thankfully the loader was also improved and should be near perfect now.

    To put it simply, it works by taking advantage of an "exit function" at game's main menu (when pressing A+B+C+Start) which normally takes you to the Saturn's CD player.
    According to SEGA's guidelines for developers every commercial release should support this functionality, however while it may hold true for 99% of them, I found at least one instance where no such thing is implemented (Radiant Silvergun) and, for that reason I also added patching for the default behavior of the physical reset button.
    So in theory it should work for all games, but for a very small number of them you'll actually have to get up off your butt and press the reset button instead :)

    As a side note and before anyone asks, if you have a boot-able cart inserted at all times, the answer is yes you'll have to boot it every time you reset, although I can implement a simple workaround for it. Instead of a full reset it will just load the CD player while still resetting the ODE, this way you can skip the cart boot and go straight to the menu.
    This will be added as either an option in a config file or it will just be automated by detecting when a boot-able cart is present.​

    That's good to know and makes more sense, at the time I didn't bother to check other combinations and just chalked it up to the fact that game came out fairly late in the console life - when no one cared anymore :)

    One other thing I forgot to mention about the exit function, is that depending on the argument that is passed to it or how it was defined, there is the possibility that in some games it will do a soft-reset or even a full reset, instead of exiting to CD player.

    I don't like getting my butt off the couch so I've been waiting for this. Will test it out tomorrow. Thanks

    Hello guys,

    RMenu 0.2b is on my one already installed and for my it works quiet well, looks nice, the ingame reset is working in 90% of the cases which is awesome, the only thing what i didnt understand was the difference between "fast boot" & "full boot".

    Next topic, after a while of using the RHEA i found out that some games are not working for example Panzer Dragon or Sega Rally, they start up, show the intro and the videos, but after the game should start they dont load up the screen stays black.
    I heard already quiet often this could be a compatibility issue as im using CCD images instead of CDi, so yesterday i took my old Padus DJ license which was still working (hororaay), download the latest DJ, but under Windows 10 it always errors after startup :(

    How does you guys convert your images to CDi? i found no other program like UltraISO, or which format should i use insteadt of CCD? Nero? Alcohol?

    Thanks for your support,

    Regards,

    Sorry, I should've made it more clear, the full boot mode does a soft reset, booting from the start of the bios splash (akin to hitting the reset button).
    While fast boot on the other hand, makes use of some bios calls to start the booting process and goes straight to the SEGA licensing screen (hence fast).
    Simply put, full boot doesn't have in-game reset support and, it is there as a fallback, just in case you find some games that don't work or have problems with the other mode.

    As for your problems with the disc images, if you are ripping your own discs then cloneCD should be more than enough, but if you downloaded those images perhaps they are just bad dumps. Anyway, both of those games you mention are working fine for me.

    I don't use windows 10, but apparently the problem with DiskJuggler is with the installer itself, as an alternative you could just use a virtual machine (XP/Seven should be fine) or check this link for a solution. Besides, you don't even need a license for it, as the demo version is sufficient for the purpose of making disc images.
    Just be sure to set the following options in the Advanced tab:
    - Scan gaps/indexes
    - R-W(CD+G)
    - PQ
    - RAW read

    Also, in case you are using Daemon Tools for mounting those images in .cue/.bin format, an older version is probably recommended, as I have seen some reports of problems with newer ones resulting in bad dumps. Personally I've used v4.49.1.0356 in a VM machine without problems in the past.

    Hi Guys,

    Only one issue I’m having...the region patcher doesn’t seem to be working for me. I have a US console and US games boot fine. When I try to boot a JAP game, I get the “disc is unsuitable” message. The patcher should be on by default, correct? I did try adding the rhea.ini file to the root and I set the “auto_region = 0” and it still would not boot JAP games with that there. I used an action replay cartridge, which worked, but I had to boot the action replay, to then boot the rhea menu, then boot the action replay again to finally boot the game. Too long a process.

    I did also have a mod chip, but I had to remove it to get it working correctly. Should the rhea work with the mod chip? I had it hooked up with a ribbon cable from the motherboard to the mod chip and then the mod chip cable out to the Rhea. It seemed to be unstable that way.

    Any help with this would be awesome - thanks!

    Set it to patch to the region of your console. Rename rhea.ini to Rhea.ini

    The new Rmenu version works well with Action replay. You only need to boot once on power on then you can use quick boot when selecting a game to bypass Action Replay. Worth having action replay always in.

    Awesome, thanks. Thought the region should have been the region of the game...makes more sense this way. The .ini was Rhea and not rhea. I just typed it here wrong.

    Good to know about the Action Replay too. How is quick boot triggered?

    Hello,

    Thanks for your help guys, i tried today to rip Sega Rally and Panzer Dragoon again with CloneCD itself, still had an old license of the good old Slysoft times and it worked directly, it seems that the CCD images doesnt like the mass converter of Ultraiso.

    Thanks for your help :)

    One more question...

    Is there a way to go back to RMENU other than a full power cycle? What about with an Action Replay?

    Is there any other reason to use an Action Replay other than for the RAM backup?

    Get the new Rmenu posted a few posts back. abc+start goes back to menu. Some games use Action Replay as extra memory, Alien Trilogy for example.
