Hi Rich, guess you're out there somewhere. I noticed a problem in MESS concerning RXB. After compiling a software list for TI cartridges, I noticed that RXB did not work anymore, none of its versions. The reason is about a year back when I actually fixed a bug in the GROM port handling. This made GROMs behave properly like real GROMs, meaning that they have 6 KiB storage space, and return some mirrored values for the last 2K. I saw that RXB makes use of the complete 8 K space. That is, I suppose it does not really use GROMs but only simulates GROMs. Questions: - Was there a real cartridge for RXB, or have you only been distributing the contents which need to be loaded in some specific way? - Apart from RXB, are there any real cartridges with a GROM simulation on-board? I know about GRAMKracker, and GK is also part of the MESS emulation. I'm thinking about ready-to-plug cartridges. The background of my questions is that I want to remove hypothetical features from MESS (like 8K GROMs or GRAMs); in turn, to allow RXB to be run as a cartridge, I can pretend that there is some real cartridge with a special "grom8k" type, and that way I can cover all these "soft" cartridges.

Hello to everyone in this excellent forum. Not everyone regularly looks into the TI-99 / 4A Development Forum, so I want to briefly inform you here about a menu program for TIPI users, which I have provided today under the following link. https://atariage.com/forums/topic/289955-mega-menu-for-tipi/ Please scroll to Message # 4 for the new version and have fun!
Hello just finished what I think is the largest game for the TI99/4A ever made. Maybe the largest program ever written for the TI99/4A as it is 960K run from a XB program. Runs from Classic99 but will have to make versions for small disks as this one takes up 3869 sectors on Classic99 at 124 files. Anyway here is the Video just made and posted:
Well RXB 2016 is being created and will be released before 2017 begins. New feature is new 24K swap using the SAMS memory card, thus allows creation of 48K XB programs running from XB memory. What does this mean? Well now you have not one 24K for XB programs, but two 24K for XB programs! Here is how it works: Normal XB 24K page of RAM: 100 CALL CLEAR 110 X=10 120 CALL AMS24K(1000) ! Switch to new 24K and goto line 1000 130 PRINT X 140 END NEW XB 24K page of RAM: 1000 FOR L=1 TO X 1010 NEXT X 1020 CALL AMS24K(130) ! Switch to normal 24K and goto line 130 Ok so how would you load these two 24K as they can not be in the same place at same time? CALL AMS24K Switch 24K presently in and to switch back CALL AMS24K will switch again to other. (Notice no parenthesis for line number.) Example: OLD DSK1.APROGRM ! Load first half of program into XB. CALL AMS24K ! Switches upper 24K to other 24K page. OLD DSK2.BPROGRM ! Load second half of program into XB. CALL AMS24K ! Switch upper 24K back to original 24K page. RUN So to recap we have anytime CALL AMS24K is called will switch Upper 24K RAM to other 24K page. And CALL AMS24K(line-number) can only be used from a running program. Now as for Variables it should be explained that nothing has changed other then programs size has increased, not number of variables or string space. But DATA statements could be up to 23K in size for XP programs to use as these do not cost string space or numeric variable space.
