Before diving into the portable version, let’s clarify what SAI 2 is. Developed by the Japanese company SYSTEMAX, Paint Tool SAI 2 is the successor to the original SAI (often called Version 1.2). While the original SAI was a 32-bit application limited to 4GB of RAM, SAI 2 introduced:

The short answer: There is no official portable version from SYSTEMAX. Any pre-packaged "SAI 2 Portable" you download from random file sharing sites is almost certainly an unauthorized crack or modified executable. However, official SAI 2 is not free

The legal way to achieve portability: If you purchase a license for Paint Tool SAI 2 (costing roughly 5,000 JPY or ~$35 USD), you are legally permitted to install the software on your own machines. To make it portable, you can manually install SAI 2 to a folder on your USB drive instead of C:\Program Files. As long as you use your own legitimate license file (saidll.dll or the license key), you are not violating the terms of use.

Warning: Downloading a cracked "SAI 2 Portable" from torrent sites or Warez blogs is software piracy. It exposes you to malware, keyloggers, and botnets. Furthermore, you will not receive updates from the developer, SYSTEMAX.
