jsTIfied just emulates the calculator's hardware, so you need to load the ROM image from your real calculator to make jsTIfied work. Many mobile browsers will not run jsTIfied properly.Ī ROM image is the software (operating system) that is on your calculator, the way Windows or Mac OS X is the operating system on your computer. Internet Explorer versions IE10 and higher, and Safari 6 and higher also work. Most versions of Firefox, Chrome, Opera will work. some browsers don't offer all of the Javascript features jsTIfied needs in order to work. This emulator won't work! jsTIfied complains about Javascript being disabled, or displays error messages about missing Javascript features.

Happily! Read how jsTIfied works: learn the nitty-gritty of how jsTIfied was designed and constructed.

Open jsTIfied on your Apple device and upload the JPEG in the 'Import Calculator ROM Image' section above.

Caution: Some very large images sent via iTunes or iCloud will result in the image being resized and corrupted! If jsTIfied seems unable to load your JPEG-formatted ROM, try emailing it to yourself instead of using iTunes/iCloud.

Alternatively, email yourself this image, then download it directly from your Apple device, or use the Dropbox App. Right-click the black-and-white square image that appears, choose 'Save As.', and save it to your computer as *.jpg.

From the same computer, click this: Create JPEG-encoded ROM image.

From a computer, upload your *.rom image to jsTIfied.
