+jedimatt42 Posted June 27, 2022 Share Posted June 27, 2022 I hate all these expansions that write on the title screen. So I finally took the time to stop my Corcomp Floppy controller from doing this. I'm not talking about the full hijack that the original DSR power up routine bestowed upon us, but rather the little bit of piddle that Miller Graphics left on the screen branding your 4A as one of theirs... Anyway... the ROM I started with can be identified as md5sum 444886597c3c8002808751688f90dcd7 - this is the 'bank 1' rom ( 1 of 2 ) Modify word at address >4196, (offset in your eprom burner 0x0196) from a value of >0200 to a new value of >1016 The new md5sum will be: 395eade664216a8b320fd0f02c421de8 This just jumps over the 2 loops that 1st clear a line on the title screen, and 2nd copy the Miller Graphics brand onto the title screen. 7 Quote Link to comment Share on other sites More sharing options...
WhataKowinkydink Posted June 27, 2022 Share Posted June 27, 2022 Interesting. I have a TI disk controller, so I've never seen this. You got a screenshot? Quote Link to comment Share on other sites More sharing options...
Reciprocating Bill Posted June 28, 2022 Share Posted June 28, 2022 I have a Myarc FDC, which has better manners. Quote Link to comment Share on other sites More sharing options...
apersson850 Posted June 28, 2022 Share Posted June 28, 2022 I have a CorComp one. Can't say I care. When I use the p-system it's not even visible. 1 1 Quote Link to comment Share on other sites More sharing options...
+FarmerPotato Posted June 29, 2022 Share Posted June 29, 2022 I used the CorComp 9900 MPES for many years. I almost forgot what the color bar title screen looked like. (Kidding) It just takes over and draws its own dark blue title screen. 1 Quote Link to comment Share on other sites More sharing options...
+jedimatt42 Posted June 29, 2022 Author Share Posted June 29, 2022 I don't have a screenshot as I overwrote the eprom I was using... My point was just to share the details of how to get rid of the MG stamp for those that experience the same sentiment... basically it is a standard title screen (with the MG rom) that just says Miller Graphics on the second line. 1 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted June 29, 2022 Share Posted June 29, 2022 The Compact Flash/nanoPEB screen notifications are helpful, though in hindsight that is probably because the device itself can be flakey. Most (all?) of the Horizon RAMdisk ROS output was removed a few years ago, partly to make way for code fixes, though I still have fond memories of the first time I saw Bud Mills fire up his TI and it displayed the MUG logo and OPA/BMS text/color changes at powerup. That was pretty neat. 1 Quote Link to comment Share on other sites More sharing options...

globeron Posted June 30, 2022 Share Posted June 30, 2022 also the BwG disk controller shows the time clock, but because of corcomp memory exp. Overwrites the title screen. Then the Snug cards also show something on the title screen. On YouTube TI99videos I probably have those as well Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted June 30, 2022 Share Posted June 30, 2022 (edited) The best solution is to use @InsaneMultiTasker's SPLASH screen in combination with a Horizon RAMdisk and his MENU program to boot. My boot sequence looks like this: Edited June 30, 2022 by atrax27407 2 Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted June 30, 2022 Share Posted June 30, 2022 It is similar on real iron in 40-columns. 1 Quote Link to comment Share on other sites More sharing options...
+jedimatt42 Posted June 30, 2022 Author Share Posted June 30, 2022 Lots of great opinions. Every 99er uses their system differently. I personally wanted to see a clean and classic TI Title screen. 3 Quote Link to comment Share on other sites More sharing options...
