Common Issues & Troubleshooting

"Failed to open archive" : The patch is named incorrectly. Rename it exactly to patch.xp3 (case sensitive).

Game runs, but no text: You forgot a font patch. Look for a font.ttf file or a second patch named patch_font.xp3.

Crashes on opening movie: The video patch failed. In KR2's settings, disable "Play movie" or set "Video decoding" to "Software mode."

Save data corrupt: Never mix PC saves with KR2 saves. The patch changes how save states are written. Delete savedata folder and restart.

Key changes (high level)

Compatibility fixes for several popular PC‑98 titles that previously experienced crashes or graphical glitches.

Improved input handling, reducing missed clicks and making touch/mouse mapping more responsive.

Performance optimizations for lower‑end devices, lowering CPU usage and reducing battery drain.

Bug fixes for save/load stability, screen scaling, and audio glitches during specific scenes.

New settings: customizable default scaling, optional frame limiting, and per‑game configuration support.

Step 5: Test the Patch

Tap "Play". The game should now:

Show clean, scaled text.

Respond to touch taps (tap to advance, swipe for menu).

Save games without errors.

If you see a black screen, the patch is either incompatible or you placed it incorrectly.

3. Video Playback (OGV/MPEG)

Many VNs include animated openings (OP). Kirikiroid2 cannot play certain video codecs natively. A patch can either disable the OP to prevent crashing or inject an Android-compatible video decoder.

Who benefits

Fans of niche PC‑98 visual novels and doujin games who want reliable playback on Android.

Players using lower‑powered phones or tablets that previously struggled with certain titles.

Users who prefer to customize controls and per‑game settings without manual file edits.
