Notes:

- Routine resides starting from $3196 in memory from the RAT2.BIN file. It uses a custom routine tailored for the provided mouse.
- Original routine still exists, but I'm overriding the final values. Patch at $1d1f to jump to first segment of HIRES routine at $6A45
- HIRES code is spread in 3 differents places in memory ($6A45-$6B3D, $6BA3-$6C65, $7850-$78A4)
- It uses 320x199 resolution
- Values for X (16-bits), Y (8-bits) and the 2 buttons (8-bits) are stored in $0AFB,$0AFD and $0B04 respectively.

RUN "BOOT" to launch

Feel free to comment for any improvement.

Have fun!
