Romraider incompatible JRE

I understand using the maf scaling tool you need Java jdk18. I also understand Romraider wont work with anything past Java 8. They said you can change how Java is referenced in Romraider. By changing the RUN.bat. I found the code and wrote it in its place it still doesn't work.

The latest version works with Java 6 thru 11, (32bit).
Use the run.bat file from here and set the java_path to your preferred Java installation.

:: Adjust java_path to javaw.exe as required for your Java system installation.
:: If the path has spaces in it make sure it is within the quotes of java_path.
:: End the path with a \ directory separator.
set "java_path="

In my case on my computer I would set it like so:
set "java_path=C:\Program Files (x86)\Eclipse Adoptium\jdk-8.0.322.6-hotspot\jre\bin\"

Do not change the -Djava.library.path entry if you wish RomRaider to work.

Well installed Java 18 for Maf 2.7.0 and JRE error again. run.bat hasn't changed. The bat file was working before installed java 18 and after. Very odd.

I thought was all good.

https://www.romraider.com/forum/viewtopic.php?f=32&t=10481Maf scaling tool. Newest version requires newer Java but previous version doesn’t.

What is the JRE error message?

Set the set "java_path=" variable in the run.bat to any version of 32bit Java between versions 6 to 11. Java 18 will not work.

Post your entire run.bat and the full path to your Java installation that is not Java 18.

Here is the bat.run file I can use to open rr until I install java 18.

Code:

:: Uncomment the line for the mode you wish to run.  Comment all other lines.
:: Adjust path to javaw.exe as required for your Java system installation
set"java_path=C:\Program_Files_(x86)\Java\jre1.8.0_331\bin\"
:: Start Editor with console redirected to %HOMEPATH%\.RomRaider\romraider_sout.log
start %java_path%javaw -Djava.library.path=lib/windows/32 -Dawt.useSystemAAFontSettings=lcd -Dswing.aatext=true -Dsun.java2d.d3d=true -Xms64M -Xmx512M -jar RomRaider.jar 1>>"%HOMEPATH%\.RomRaider\romraider_sout.log" 2>&1

:: Start Logger
rem start %java_path%javaw -Djava.library.path=lib/windows/32 -Dawt.useSystemAAFontSettings=lcd -Dswing.aatext=true -Dsun.java2d.d3d=true -Xms64M -Xmx512M -jar RomRaider.jar -logger 1>>"%HOMEPATH%\.RomRaider\romraider_sout.log" 2>&1

:: Start Logger in full screen mode
rem start %java_path%javaw -Djava.library.path=lib/windows/32 -Dawt.useSystemAAFontSettings=lcd -Dswing.aatext=true -Dsun.java2d.d3d=true -Xms64M -Xmx512M -jar RomRaider.jar -logger.fullscreen 1>>"%HOMEPATH%\.RomRaider\romraider_sout.log" 2>&1

:: Start Logger in Touch screen mode
rem start %java_path%javaw -Djava.library.path=lib/windows/32 -Dawt.useSystemAAFontSettings=lcd -Dswing.aatext=true -Dsun.java2d.d3d=true -Xms64M -Xmx512M -jar RomRaider.jar -logger.touch 1>>"%HOMEPATH%\.RomRaider\romraider_sout.log" 2>&1

When I install Java 18 I get the JRE Compatibility Warning box.
Incompatible JRE detected.
RomRaider Editor requires a 32-bit JRE for full feature support.
RomRaider will open but when I select logger I get same error and when click ok it closes.

If I uninstall Java 18 its back to normal

You are missing a space after set.
set "java_path=C:\Program_Files_(x86)\Java\jre1.8.0_331\bin\"

But is still won't work, you need to use the version posted here: https://raw.githubusercontent.com/RomRa ... ts/run.bat

OK, so I've read thru this thread.

I gotta be honest, its been a while since I was here and need some pointers on how to fix this.

How do I access the run.bat file?

dschultz · **Posted:** Fri Apr 29, 2022 7:13 pm

Open in Notepad.

Thank you dschultz!!!!!!! I finally got it working. I ended up using file you linked. Used "java_path=C:\Program Files (x86)\Java\jre1.8.0_331\bin\" no underscores. Used the run.bat file to open, created a shortcut for the run.bat on desktop and everything is golden finally. I Have RomRaider and can use the newest MAF Scaling 2.7.
