When I try to load a file to ROM and RAM, I get this error: Exception in thread "AWT-EventQueue-0" java.lang.StringIndexOutOfBoundsException: Range [0, 960) out of bounds for length 24 at java.base/jdk.internal.util.Preconditions$1.apply(Preconditions.java:55) at java.base/jdk.internal.util.Preconditions$1.apply(Preconditions.java:52) at java.base/jdk.internal.util.Preconditions$4.apply(Preconditions.java:213) at java.base/jdk.internal.util.Preconditions$4.apply(Preconditions.java:210) at java.base/jdk.internal.util.Preconditions.outOfBounds(Preconditions.java:98) at java.base/jdk.internal.util.Preconditions.outOfBoundsCheckFromToIndex(Preconditions.java:112) at java.base/jdk.internal.util.Preconditions.checkFromToIndex(Preconditions.java:349) at java.base/java.lang.String.checkBoundsBeginEnd(String.java:4602) at java.base/java.lang.String.substring(String.java:2715) at DisplayPanel.actionPerformed(DisplayPanel.java:158) at java.desktop/javax.swing.Timer.fireActionPerformed(Timer.java:311) at java.desktop/javax.swing.Timer$DoPostEvent.run(Timer.java:243) at java.desktop/java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:318) at java.desktop/java.awt.EventQueue.dispatchEventImpl(EventQueue.java:773) at java.desktop/java.awt.EventQueue$4.run(EventQueue.java:720) at java.desktop/java.awt.EventQueue$4.run(EventQueue.java:714) at java.base/java.security.AccessController.doPrivileged(AccessController.java:399) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:86) at java.desktop/java.awt.EventQueue.dispatchEvent(EventQueue.java:742) at java.desktop/java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:203) at java.desktop/java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:124) at java.desktop/java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:113) at java.desktop/java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:109) at java.desktop/java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) at java.desktop/java.awt.EventDispatchThread.run(EventDispatchThread.java:90) The code I want to load is this: ASM: start: lda #$ff ldy #$ff ldx #$ff Hex: A9 FF A0 FF A2 FF Thank you!

Could you attach the .bin file you are trying to load?

Github doesn't allow you to upload a .bin file directly to the thread, so I uploaded it to this repository: https://github.com/Luc-cr/ASM-6502-Test

Ah. Like the actual ROM, the emulator needs a full 32kb file for either the ROM (or RAM). This is because the RESET, IRQ, and NMI vectors are at the very end of the address space, and the CPU needs to read from that location on startup/reset. Ben's videos go more into this. I'll add a handler for that case, with a more descriptive error.

Ok, Thanks for helping me.
