  1. nope, the problem chips commonly get a heatsink added to help cope, but fans arent stock and are almost never added
  2. i hadnt realized it was the actual cartridge that got the chip change that made for the model swap, how do you tell which ones you have? also, dont these things have a noticeable failure rate, maybe the static discharge issue isnt the only thing plaguing them nowadays and they could be running a bit hot in some cases, just look at what hot running has done to the commodore 64
  3. huh, if it really is only a current issue and not one of voltage then it will probably work fine, as previously mentioned modern batteries are much better than they were thirty years ago so a single battery now might be able to do what took two back then, heck, it might even be damaging to use two now with the larger battery capacity depending on how the system links them and actually draws from them, over amping isnt an issue that happens in a properly designed circuit but who knows how these were engineered back then, the first try at a technology tends to have a few bad design choices
  4. i dont claim to be an expert and i could be wrong, particularly with the difference in batteries over the decades, but ive tried using other types of things with insufficient power supplies and while some of them might look to behave initially they end up with various glitches or things not working at all, as an example of this someone got a nes to run off a 9v battery and it just kept going till the battery was dead but the graphics portion of the cpu got progressively less and less coherent till power failed, if im being honest it looked kinda cool so it could be worth seeing how low i could dial down a psu with it still turning on
  5. it might run, but it would do so poorly if it does and more relevant to your problem, any way of bypassing the second battery would use the same skills and tools as fixing the broken terminal, connect wire to busted terminal via preferred method, route wire to where its supposed to be
  6. not quite but that is most of the way there, i wouldnt have found that since its in the russian domains, but regardless that does appear to handle most of the hard steps to making a proper flash cart, mv is one of the few retro consoles not to have something like that in circulation, though with the maintenance issues its not surprising. i guess since all the hard research has been done its just a matter of someone with the technical savy getting all the details put together into a final product
  7. i mean something that you could load different homebrew games onto, or copies of the original, but thats a side concern, i dont see it being too complicated since the cartridges are the processor anyway so making a small computer that outputs to the microvision screen and powered off the internal voltage is all it would be, maybe a small extra display for rom selection, but thats not really needed, the real trick would be in how to set up the button and screen overlays
  8. does a flash cart exist for it yet or did the screen problem cripple interest in development on that? emulators are fine but i always prefer original hardware, the controls are usually better for one thing
  9. ive never seen a working microvision, only poor images and the box art, how close is that screen prototype?
  10. im assuming the backlight in question would be of the luminous film type, or whatever its called so its quite thin and since not all the original polarizers are needed anymore that frees up some space for a thin backlight sheet, but its nice to see this finally moving again, the one ive got is in the typical state of totally shot and its really no surprise the samples didnt survive shipping, they seems to have been quite sensitive even new and its only gotten worse
  11. yeah thats about the right symptoms, technically other things could be wrong but its such a common issue that its not worth looking for another cause
  12. this doesnt sound real, but it would be nice if it were, the lcd degrading has something to do with the shoddy manufacture and sealing of the original crystal material, it might be able to increase the brightness by acting as a reflector, that might have helped years ago, but unless you do something chemical/electrical with it i dont see how that would do any good now that they have degraded as far as they have now edit: can confirm, the stock reflector is also crap, mine was nearly a flat dark grey instead of metallic, sadly the lcd is still shot regardless, but an interesting detail to find. also apparently the lcd pattern is still visible and mostly intact within the screen even though its not any good anymore
  13. fair enough, i knew about the cartridge processor, but the lcd controller is often described as a processor so my confusion. it doesnt have that many pins and it seems that its a fairly simple input format, do you think it might be possible to use an led board instead of an lcd? it might be easier to produce and its not like the pixel count is high enough to shoot the idea down immediately and it seems like it could be interesting
  14. my understanding of it is that there are two processors, the one on the main board and the one with the game stuff on it on the cartridge, the console one was originally a higher spec one that needed a higher voltage, but the later replacement while less capable needs less power and apparently the split processing meant that the games ran fine despite the downgrade, that or the first one was overkill
