Any help on picking up the porting to pinetime?

hi,
previously i bought a p8b but it's a mirrored version,
i installed espruino as in the eucwatch;
except the mirror-ed screen, things seems working i.e. bootup, connect to private store of p8.

i got a sealed pinetime so cant do developement,
i am consider buying a bangle.js v2 and forget about pinetime,
or but a pinetime dev kit and try agian.

i saw from eucwath or else, the p8/pinetime espruino is just v2.14 vs latest v2.19,
any one can comment is it hard to pick from what others have been done?
i.e.; to install the ported espruino on pinetime,
and update the espruino appropriately.

if i got money, i'll buy a bangle v2 + pinetime dev kit.
i still wish espruino to happen on pinetime, as pinetime is cheaper, have color display, and i believe pinetime would be available for a longer time -- their development cycle is slow, and bangle.js v2, althought is a china tailor-ed model, may not be available at all times.

thank you.

ps: i got some 3 month college programming knowledge, and rely on gpt4.
